I always have problems with WM5 memory management, which led me to experiment more on some free apps out there. This is a personal trick I just recently learned from all the AKU 3 versions that are coming out that I have been trying out and would like to share with everyone.
I will attach OXIOS Memory CAB file below my post, you need both Oxios Hibernate and Oxios Close Apps for this trick to work.
This is the theory for the increase of memory: basically what I wanted to happen is to only have 1 application running in the background no matter what. Thus, opening another app automatically closes the other app, even just pressing the OK button. Just like what a Palm device does with regards to application handling.
One draw back though, you are eliminating the ability of the WM5 device to run multiple applications at the same time.
OK enough of the explanations, here is what you have to do:
1st: Download the copy of OXIOS apps I provided.
2nd: Run the CAB file to install.
3rd: Go to Windows>Start Menu>Programs>Accessories.
4th: Copy the shortcuts for both Oxios Close Apps and Oxios Hibernate.
5th: Go to Windows>Start Up.
6th: Paste both Oxios Close Apps and Oxios Hibernate.
7th: Perform a soft reset.
Basically this would make WM5 behave like a palm device. You can now only open one application at one time, thus ensuring you have enough memory for your current application to run.
You don't even need to close any app anymore manually, since it is done automatically for you now.
There are some exceptions to this however and they are:
1: Contacts Application
2: MMS Application
3: Calendar Application
4: Phone Application
These 4 apps can be opened all at the same time without closing automatically, a good thing because you want them to work together when sending messages or files. Plus, you also want the phone ON at all times.
Good luck and let me know if you prefer this solution or suggestion.
hmmm...
I don't like the idea of not being in control of my device...
I've been happy doing it manually with Magic Button, and since yesterday, Wisbar Advance 2.
I think the extra tap is worth it!
that's great, maybe it's good for me, thanks for your cab file.
i tried these apps before, but not in this fashion. it never really fully recovered all the memory that it was trying to recover.
is there still a gradual memory leak, or does this manage to retain the full amount of memory after each closure.
i start with 29 - 30mb, it drops to about 18mb, so I reset it. does this stop the memory drop and reduction and totally reclaim the memory on closure of every app?

No, unfortunately, but based on using them on the latest AKU 3 ROMs, Oxios apps are getting better in recovering the lost memory.
thanks! will think about installing this. currently, im just using memmaid's reclaim ram plug in. Im not sure if it's just placebo but it works somehow..
What is up with the memory drain on this device. I'll start the day with 24mb of memory (soft reset) and only have 10mb or less at the end of the day with no apps but activesync running. Has anyone less notice this?

Yea I get the same problem. Except I start off with about 20 and end up with as low as 9 before i'm forced to soft reset.
Its the magic of the Mogul's memory leak. The old rom and new rom feature it so untill a new update comes out, were stuck with it.
Does the Hermes and Kaiser have the same issue? They seem to be similar. They other thing is that the WM6 is suppose to have made those apps that leak in previous versions run at the kernel level.
my titan doesnt have the issue. its an app you've got installed. hard reset and dont install anything, you wont have the problem. troubleshooting 101. dont blame the titan.
I posted this on another forum discussing this problem, so I'll just quote myself here:
The memory "leak" thing is nothing more than a cache "optimization" in place to make the device respond snappier.
Whether it succeeds or not is another story altogether...
Basically, like any cache, it stores recent calculations for faster response later. For example, if you open and close IE alot, you might notice that the first time you open it on a fresh restart takes a little bit longer than the next times- that's because the second time you start it up, parts of it are still in memory from the first time!
You might be wondering why this happens even after forcing it closed with Xbutton or the memory settings. That's because the info stored in the performance cache aren't directly related to any one program! Many apps can use the same routines and calculations, and therefore this process exists on a processor/file system layer as opposed to a software layer, and therefore also exists even when all programs are closed!
Meaning, if I have mapopolis that uses a certain routine to access my BT GPS receiver, even after I close it, some of that routine stays in memory because perhaps Google Maps will use the same routine, and therefore respond faster!
Now, ideally, this should speed up performance, and it SHOULD disappear on its own if the memory is needed and the information goes "stale" (hasn't been processed in a while = not really needed for optimized perfomance). However, one look at the way Microsoft handles "automatically closing apps" (native X button, anyone?) is enough to know that WM can't manage its own memory very well.
I can, however, vouch for the fact that the longer you leave all programs closed, the more of your memory starts to creep back into available. I've sat and watched this happen. So, it sort of works, but perhaps not well enough if people are having low memory system crash problems.
Now, before you all start blaming MS for this... Its not Microsoft's problem. They developed CE-5 (which WM6 is based on) on machines limited to 32MB to make sure the programmers didn't get lazy with OS bloat.
Its the manufacturers who add all this file system optimization and stuff to their final device. In this case, its the way HTC thinks the system should run, which is why this anomaly is NOT as apparent on, say, a WM Treo device.
The good news is that if we complain enough, HTC might realize this optimization does more bad than good, and leave it out on the next ROM update for us.
However, truth be told, I think it works. The Mogul is one of the snappiest PPC's I've used of late, although I can't say for sure if its because of the cache or not.
This is just my personal opinion, so don't flog me! I just don't look at the memory useage anymore unless I'm having a problem, which mind you, I hardly do.
My most recent observations were this:
Soft reset gives me ~21MB (got some htc plugins), and after a day of use, making sure to close everything after I'm done, I get 18-19MB. At lowest, I hit 10MB after closing alot of apps. This memory usually comes back to 18-19mb in a matter of time for me. If for some strange reason it doesn't (can't say how often this happens), I soft reset.
All in all, I'm happy with the Mogul.

I wasn't blaming the Titan directly, although I wish they would allow you to adjust the memory like they have in the past. But as I've read that may having something to do with chipset of battery consumption.
I was just wondering if others had the same issue and might know of the reason.
Is there a list of known apps that cause memory 'drain' or don't clear their cache. I can understand apps caching data into memory to run faster, but they are not cleaning themselves out upon exit. The strange thing is how they continue to grow over the course of the day with no interaction.
I'm doing a hard reset to see if it get better. Add apps one at a time until I find an issue.
Ok did a hard reset. Setup Outlook to get my mail from Exchange and Gmail. Let it get synced and then did a soft reset. Started with 24mb after reset, down to 21mb without doing anything after an hour and it's still falling. The only thing running is ActiveSync. I've also removed htc_cm_guardain and ssdaemon from the startup. The only thing in startup is poutlook.
The thing I noticed when I had handyswitcher installed (before hard reset) was that filesys, device, gwes, services, shell and cprog all continously increased there memory consumption over the course of a few hours and never stopped or released it.

No no no... the reason you used to be able to select storage vs RAM was because it was SHARED memory! It was actually all RAM. If you had a 64MB device, that 64mb was split between ram and storage, and just like the rest of your RAM, it would wipe out when the battery died!
Ever since WM5 came along, they stopped sharing the memory, and now have dedicated RAM and Storage (using the leftover space on the EPROM chips used for the ROM image), much like a computer. This is a much better solution since you don't sacrifice your RAM for storing some large files, and you don't have to worry about battery failure cleaning you out!
Also, its not the apps that have cache, its the file system. The file system WILL actually free up some of that memory as the device is left with all apps closed for a while (maybe not all of it, but I've watched my device go from 11mb free after closing stuff to 18-19mb).
You guys need to hit the easy button on this one! It may not be a permanent fix, but there's a small freeware called Oxios Hibernate that releases RAM. I just put it on my start menu and 2 clicks....I have free RAM. Try it out, you won't be disappointed.
bam, thanks for the info... that little app rocks.
use a file explorer and go to \Windows\Startup. There is a shortcut there for a program along the lines of HTC_Guardian_cmsomething. This app is a htc app used to enforce sprint settings and runs in the background. So long as you don't destroy your phone internet settings you can just remove the shortcut. I found all my memory leak issues have gone away. I don't have any leaks when using the kaiser tab plugin.
Yes I've removed the links for HTC_Guardian and SSDaemon from startup and added them to my settings folder (if I ever need them). I soft reset to around 25mb and the Oxios Hibernate app keeps me around 24.5mb.
what does SDdaemon do?
sddaemon is suppose to be the speed dial or voice command app you get when you hit the button on the left side with the talk bubble. It loads the app if you hit the button, so I'm not sure why they have it in startup.
On my old Treo 700W, which REALLY had a memory problem, I used Oxios hibernate all the time. It works quite well.
yes, it works.

I am using aserg windows mobile 6.1 rom and I have noticed a creeping problem. As time goes on, I can only seem to run 1 substantial program at a time.
For instance, if I try to run any of these programs in tandem:
HTC audio manager or Windows Media Player
Mundu mobile messenger
Opera
Internet explorer
Dictionary software
Outlook mail (sms/email)
Skype
the program in the background always closes. This is especially annoying when for instance I am listening to music and I get an email or sms, I go to check it and my music player just closes. Same if I try to browse the web and listen to music or check an sms, It is very annoying.
What causes this function in windows mobile and how do I turn it off?
As for memory, when I start I have 13-14 megs free memory. Any of these programs take an absolute MAXIMUM of 4-5 megs at peak usage. I should be able to run at least 2 together without a problem, and if another one does nto have enough memory, it shoudl just say so and not start, but not close out other programs...
I also have about 4-5 megs of free storage space on the phone.
any ideas on this one?
It seems as time goes on, I can't seem to run any more than 1 program simultaneously...
Reduce the amount of file space your browser have allotted for cache files and history.
My browser cache for both Opera and PIE are both pointed at the storage card which has about 500megs free. This problem occurs even if I am running any programs though, not just browsers...
It's either the memory shortage (which some of those programs can actually take much more than 4 or 5 mb to run.) Or you have it set to close on tap, within the task manager/x-button, instead of close on hold.
I use batterystatus, and it is set to tap and hold X to close, but I never use the X, I simply go to the start menu and open another program, then when I try to switch back to the other program, it is closed already.
How do I check if it is a memory problem?
For instance, if I run HTC audio manager, then get a message, I click reply, then after about 3 seconds into my reply HTC audio manager closes.
is there any way I can "force" the programs to stay open? Even if I were to launch a new program and it does not have enough memory, it woudl just not open rather than closing an existing open program...
To me, it sounds like you are running out of RAM, and programs that were running in the background are automatically closed. I'm not affiliated with Windows Mobile and hence not an expert, but I believe this (closing previously open programs rather than the new one) is the expected behavior in WM. Imagine getting a phone call and the phone app not opening since there's not enough memory because the OS didn't automatically close background programs...
I don't know of a way of changing the memory management behavior, but maybe someone else here does? I'd argue that you wouldn't want to anyway.
I'd suggest that you DO use the X button to close programs, otherwise I guarantee you will run out of memory and things will close automatically anyway. The difference is you won't have any say in what gets closed at that point. I added programs that I don't want to close with the X button (like Live Messenger) to the exclusive programs list in the Task Manager.
Second, I'd suggest you take any steps you can to increase your original pool of memory.
Darren, I understand your point, but it seems as if I have plenty of memory, and I can only run 1 program at a time. I don't mind so much the behaviour, it is just at the point of being ridiculous when I can only run 1 program at a time.
So you think that starting with 13-14 megs of free memory is not enough? How would I go about increasing this original pool of memory?
Also, even it I use the X button to close programs, that does not solve my problem anyways, whichever program is not in the foreground seems to close by itself anyway...
phony, I understand your frustration. I have had low memory problems myself, and I know that programs running in the background will close when that happens. That's why when I read your post it sounded like a memory issue to me.
I ended up tweaking a few things to try to get more free memory, like not running certain processes or services automatically at startup. I'm not sure if it is relevant to the ROM you are running, but see http://forum.xda-developers.com/showthread.php?t=312312.
This is definitely a memory problem. When the free program memory is lower than about 1MB (don't remember the exact number), the WIndows Mobile will send a WM_HIBERNATE to all the running program to release all the possible resources. If the memory goes lower, it will broadcast another message called WM_CLOSE to close all the background apps to release more memory. The only reason for apps that close on themselve is either low on mem or there are some apps in the background (maybe a virus) sending WM_CLOSE every now and then. To be honest, to have less than 15 megs of ram to start with is NEVER enough. Try to change the pool size if you don't like any of the great roms here. Hope this help.
My phones lately been acting funny
programs have been fore closing and its been laggy and idk why i did put any new apps..
dont know what iv did different i never did anything i have dxtop but it never did anything before
my phones moded and rooted and all the other stuff JF released
If you have a lot of apps or if you're running low on internal phone memory, it would cause your phone to lag. There is also a couple more reasons, I just can't think of em at the moment. =/
You ned task manager. Look which programs you've got running, may be you don't need some of them. I know for sure that "phonebook" app and "mybackup" app are some serious memory hogs, my phone was acting all goofy, uninstalled those two-problems are gone and forgotten.

And i happen to have both of them..........well how do I check my internal memory..I have dxtop memory widget and always says around 24 to 26 mb free of memory..so u think i should remove those 2 apps? i mean my back up i can always reinstall but i have that nadroid backup thing when i got my phone rooted to do a full system backup to my sd card

Don't quote me on that but....
24-26 mb of memory is probably available for app installs (that would be system/data/data part of your phone). Running programs occupying different part of the memory, think of it as a RAM memory on the computer. Android has it's own program to decide which processes will run in the background and which wont but it's too immature at the moment. It'll get better with time.
With that said, phonebook, mybackup and in your case dxtop are all running constantly on your phone along with gmail, myfaves (whether you like it or not), maps, messaging, and bunches of others. Something is coded in them to prevent android to shut them down. Lock 2.0 is another one that runs in the backround all the time but it's not that memory hungry and doing just fine by itself.
The best way to check what's running is to download "Task Manager for root users" from the market (it's free). It will show which programs are running at the time. Click on any program and it will show the option to shut that program down. but if you shut down phonebook and hit refresh you'll see that it will restart itsef.
I suggest that you get rid of the phonebook, it looks very very nice but can't make it default so what's the point? Backup is waste of space too, you can back up all the info other ways so again, what's the point?
Good luck, I'm sure you can figure it out and reclaim the speed that G1 is capable of. Sorry for taking so long to get to the point.
Oh yeah, Imeem will run in the background indefenately as well.

Well got rid of phone book and my backup since i can always back up my full system
and I already have advance task manager and i can close all the applicatiosn running but not proccess or services with that said I always have close everything app and run that once in a while
I noticed that with dxtop(trial) that every time I went to the home screen, either by hitting home button or backing out of an app, there was a lot of lag. And this is before the little countdown timer the trial has in it.
Uninstalled and am in the process of trying out the other two home replacement apps. Dont have that problem with them. If you are still having issues might try unistalling dxtop.
I probably shouldn't even ask because it was covered many times but.... do you have your caches on sd and if not do you clear them often?
how do i close programs running in the background. i know i have to hold home, but wat do i do to close them.

Can those of you that notice screen freezes check your available memory at the time of the freeze. Im noticing that my build works perfectly until I get under 190mb available and it get progressively worse with the more memory in use. At around 100mb I start getting long wake times.
I have also removed three screens of icons and widgets to stop items from reloading after I kill the app. I have also reenabled my gsensor and auto-rotate (I had used gscript to disable it). Again as long as my memory stays above 200mb the system is GREAT, even with the gsensor active.
I did not notice any freezes after initial load, but as I started accumulating apps and widgets I think I have hit a choke point with memory.
I hope I am on to something.
Also, Im using TasKiller to kill apps with "Kill on Screen Off" enabled.
I am interested in seeing what people are experiencing. As I have stopped using task managers and have reverted to allowing android to do its thing. I have also turned of the screen rotation. I do not experience long wakes or screen freeze normally.only when my setcpu power profile falls below 572mhz do wakes become slower.
I tried to stop using task killers but i cant uninstall TasKiller as mattc has put it into the ROM so if I uninstall it it comes back on reboot. So I figure if he put there, it must be worth using.

You would think that but I dont think people have an understanding of how android works vs winmo. In winmo Apps run all willynilly and dont shut down when memory is needed.
I will do my best to explain basic over view as i saw it
Your home screen is always in memory as it is considered a frontend app.
When you open a app it keeps the home screen in memory.
Now say this app is gmail. gmail opens and you open a link that opens a web browser. Now Say you decide to open a game but you have no more memory.
Android decides which app can be killed to make room for the new app.
since gmail was opened prior to the browser it is considered the oldest.
Android creates a saved state as you will. But only of the position in which you were at in gmail. It can then auto populate that info at a later time.
Then once you are done with the game If you press back it will bring up the web browser. If you press back again it will access that gmail saved state to bring you back to that point in the app killing off the game as its un-needed.

I'm not running out off memory, it's that memory is getting really low. That's the part I don't understand. I have a gig of system memory, where is it all going? How do I get down to 100 meg when I have nothing running? I'm trying to research android memory usage so I can figure this out. I know that since I started keeping my memory above 200... zero screen freezes. That speaks volumes to me. I wish I understood more.
