Understanding loss of Program memory

I have built a ROM using Pandora kitchen. When I start I have 20MB of free memory.
I was getting problems with programs not starting due to lack of memory. When i checked the free program memory it was down to 2MB.
I had no programs running and use 'x' button to clsoe all programs not minimize them. On a soft reset I am back to 20MB.
Where is all the memory being used and is there a way to stop it?

No surprise there... It's windows!
I think it is because of WM6 not releasing memory properly or in a timely manner. I use Pandora 9.5/3.62.3 and I still see it myself. What I do is that I run Oxios Hibernate or Oxios CloseApps every now and then. Best that I could get back is up to around 15-18mb after a full day's usage. Just do a reboot every now and then.
Oxios is quite good. It allows me to reboot less often now. I've included the cab file below. Hope this helps!

Addendum...
By the way, Hibernate frees memory without closing applications or disturbing the internal state of running programs. CloseApps frees memory by closing applications that can be closed and by GCing as much as possible.

More on Memory leak here.

I tried Oxios and it isn't helping.
I get such fast memory leakage I get about 1/2 day use before a reboot.
Is this caused by the base ROM or by one of the apps I'm loading with Pandora.
By doing a trial and error install with various programs on the same ROM could I find an app causing me the problem?

I think its because of the ROM, maybe do a hard reset or try other ROMs. I have never used pandora, but the ROMS I have used and using now, has about 28 on cold boot. It usually stays around 23 - 24 with limited use.
Also, check the page pool size. I prefer 4MB as I run GPS program which needs a lot of free mem.

when applications does not free malloc'd memory and terminates, WM does not do any clean up (at least not immideately).
so if you have a badly written application you are using quite often, free memory drains fast.
to simulate this behaviour you can execute the attached applicaton.
it allocates 1mb of memory displays a senseless messagebox ad then it terminates (it does not free the malloced memory). when you started the application ~20times your memory is no longer available and you have to restart your phone.

Rose rom memory leak?

Does anyone else's memory seem to disappear after the phone has been on for awhile?? If so is there any fixes??

Start\My Tools\Free Memory or you can use CeleTask or SKTools, you will not regane all the RAM so a soft re-set once in a while will gain it back.
M$ phones tend to have leaks no matter what ROM you use.

memory leak.
Stylez is right, I use rick's v24 and I use the celetask to free up memory after closing apps with task mamager just to keep the mem. fresh, but also after a while you start getting less and less free memory back so a soft reset gets you back to the most memory like stylez said.

Try decreasing your page pool with the method described by stylez in their ROM thread... Currently the low amount of RAM is the only thing that sucks about the excalibur as a phone I'm glad I got the Touch Pro where that's no longer an issue at all.

i had the same problem with the rose rom. Even closing all tasks and freeing memory didn't help after a few hours....it was either reboot or I couldn't open programs. I eventually went back to the other rom I had..... I like the Rose rom though....very clean...very simple. Just couldn't do with the memory problem.

Well the problem with the high memory utilization of the Rose ROMs, guys, is that all the applications in the Rose ROMs were intended for the S740 "Rose" device which has 256Megs of RAM. Our Excaliburs only have 64... While on a S740 this wouldnt be a problem at all, it is for the Excaliburs. My advice is to kill all the apps you dont need running the background, including all extra processes, like the htc weather service... etc

NRG, is the htc weather application removed from the superlite rom of yours? that ROM looks good, might have better battery life than regular rose roms. thanks.

It's not removed, but it can be easily disabled with a registry edit

Or you can always reboot your phone if you tend to have a decline in memory... this is what I always do and it has worked out for me just fine...

Memory management on WM6.1 ?!?

Using the NRG 1.4 ROM and loving it! Also, the built-in CeleTask util is awesome!!! Still, I would love to have the memory management happen more automatically. Is this possible? Anyone know how to schedule a nightly "close all tasks" on the phone, or a "free memory" task that runs a few times per day? Can I assign the CeleTask "free memory" task to a speed dial or shortcut?

Two choices:
1. Write a Mortscript (requires learning how to write scripts, not all that hard)
2. install SKTools, it has an automatic cleaning option that closes tasks, cleans temp files and the like.

Thanks, Bupahs. I wasn't aware of SKTools, but it appears that they have a tool called FreeUP RAM service that is available for free with their "lite" suite.

on the RAM note, my NRG rose rom 1.7 by ricky and styles seems to leak memory while its on sometimes and im always forced to restart when i havent ran anything besides starting it up. sometimes this can happen in less than an hour! help?

I think you will find something else to it as still only a handful of users state this, i personally have not been affected by a leak needing a reset in less than an hour, same as many users who are still in contact with myself and are happy users, i know there has been reports and also am aware that the Rose has more available memory so will use more since it's ported, but since i play music and have weather diaplayed i can't say that you can state this to be a leak in the ROM, 2000-3000 uers of 1.7 alone and still only a handfull of users complaining of this issue.
Not at all stateing you and users some other don't have issues, just stating that i think there is more too it than meets the eye.

6.5 Insane RAM usage?

I have tried multiple 6.5 ROMs including multiple EnergyROMs and even the official HTC 6.5 ROM and they all have the same problem. Very high memory usage. It just keeps climbing. After one day of pretty normal application usage, I'm at only 40MB free. And having Windows Mobile close things when there is still 20MB free doesn't help either.
gwes.exe starts at below 15MB but blows up to 30MB. What is taking those 15MB? Nothing extra is running then after a soft reset.
Is every 6.5 ROM like this?
Also can I change the limit to when Windows Mobile starts closing programs? It seems that it is set to a percent not a fixed amount of megabytes.

I should start by saying that I'm no expert, but this is my experience:
I think that some ROMs have better memory usage than others...but this definitely is a commonly-reported problem with lots/most ROMs.
With the current ROM I'm running the memory stays high (>70%) even after a Level-3 clean with cleanRAM -- only a soft-reset releases it.
I've been running WM6.5.1+ ROMs for the past few weeks, mostly Sense 2.5 versions...and I don't remember if milder ROMs are better. I have Activesync (and data) constantly on/connected to my Exchange Server, so maybe that makes it worse -- don't know.
I guess I'm just assuming/hoping that later/more-refined builds will have better memory-management...until then I just put up with it...and soft-reset when I feel like it.

Does anyone know what specifically causes this? I tried pretty much the same EnergyROM on both my Rhodium and Raphael (when I had it) and the Raphael didn't have any of the memory problems the Rhodium has. Same OS version.
Edit: Found this on ppcgeeks, going to try it out.
HKLM\Software\HTC\ResProxy
"ShareMemSize"
Change this value to zero
ResProxy is HTC's method of "Pre-Caching" your applications on the phone, therefore loading times are faster when opening, etc. It just allocates a chunk of your memory for this feature. Problem is, after about a day of not soft-resetting your phone, your idling at 90% or so.
Changing it to 0 will set this as DYNAMIC. So instead of a bunch of pre-set apps being precached IMMEDIATELY, it does it dynamically. It will only raise the memory for the apps that you are currently using, etc.
Keep in mind, changing this REG does not affect speed in terms of opening applications,etc. Performance stays identical.
You will not notice IMMEDIATELY that this tweak has worked. You will notice later in the way when you notice your device won't idle higher than 65-70% usage anymore, and won't even get as high as 90% unless your running mad software on it lol.
Enjoy!

It makes a huge difference in RAM available when the phone first boots, yet things like the album and calculator are still launching instantly. What useless stuff does this thing do?

Flash a ROM that cares about your memory.
Disabling push internet and resproxy helps in stock rom, but the memory usage will be still high.

In my opinion the WM6.5.x branch uses less memory comparing to WM6.5 branch. However, this is nothing comparing to what a chef is able to manage.

Turn off the WM6.5 lockscreen, it uses a lot of memory as gwes.exe. I may provide you a cab if you wish.

could you please explain how to turn off wm6.5 lockscreen ?
and also what is gwes.exe what is it for & can it be turned off as well ?

If you are still using Energy ROM, using one of the Start Menu replacement options yields big RAM savings. But aside from that, Energy is not "lightweight" in the RAM department. As Jackos suggested, you might try other ROMs.

gwes.exe controls all the window elements. Basically, it is the GUI.

The gwes.exe cannot be turned off, just like Miami_Son wrote, it's managing the whole GUI.

Just a simple cab that disables the lockscreen in registry. Changes only one registry key.

[Q] Ram decreasing throughout the day Normal?

Hey, I'm running the stock rom on a At&T Tilt 2, most of the time I am using TouchFlo3D, once in awhile I'll switch to SPB Pocket Plus (Demo Version).
I notice when using TouchFlo3D I start with ~70MB of Ram after a soft-reset, but as I go throughout the day this takes a Very Fast dive, just using the program for messaging, etc.
When using SPB Pocket Plus (Demo version) I start with ~90MB and it keeps it up for much longer throughout the day...no need to soft-reset all day to bring it back up.
I know this would happen with my Samsung Epix running WM 6.1...but never to the extent of the Tilt 2, barely anything would fall off, I would never need to soft-reset just to get my Ram back throughout my day.
I always check my task manager too, making sure nothing stays running in the background.
Is this normal with the TouchFlo3D interface?
Anyway to free up more?
Thanks

it's a common issue with windows mobile phone to have these leaky ram. The stock rom seems to have more issue in my opinion. I think mail and also windows media will never fully close themself after you launch them.
Stock rom uses a bit more memory because of some bloatware that often got loaded. Though the latest rom (not officially out on att or htc site) seems to have less issue with slownees but still has leaky ram.
My opinion is that if you are concerned about hte ram leaky or slowness, try one of the custom roms, they often works better, faster, and took out most of the bloatware.

I had the tilt2 for about 6 months, I noticed some memory leak, but no concern, since I never had an issue with it, but since a few days ago I noticed that after turning the phone ON I have 35mb storage ram and 80mb program ram free but I can see the program memory going slowly down to 40mb and sometimes to 24mb in 20-30 min. Without ruinning any app!
What's running there? that I can't see.
I have stock At&t ROM and the 8gb MicroSD with as much I as can, pictures, videos google, bing, music, recordings etc. QUESTIONS
How I delete some of the at&t garbage with out using a custum ROM? (I don't know too much to do that)
Is there an app to manage the stolen ram?
I have over 1000 contacts, and gmail,live, hotmail and msn emails, can I move that to the microSD? how?
I would appreciate your help.

I have a lot of contacts...but keep them all on the sim memory, I only copy over my main ppl that I talk with daily, so I can have their pics and set ringtones for them individually...a start to help with memory.
I have an 8GB card too...my memory isn't that low...the ram goes down throughout the day...faster than my last windows phone....try installing apps on the storage card verses the main memory...what I do when I can...have about 120mb of memory left on the device.

Download Crudscraper to remove nearly all traces of bloat AT&T added.
See my sig for results.
Consider investing in Mem Maid to keep on top of maintanence.

No program can remove things stored in ROM (including CrudScraper, which basically only deletes the shortcuts from the Start menu). The only way to actually get rid of the bloatware is with a custom ROM.
TF3D is a known memory hog with a lot of leakage. The new OEM ROM's version of Sense is just as bad. That's the price you pay for pretty home screens. The free CleanRAM is a good way to reclaim RAM during the day, but soft resetting is still the best way.

There's 226.05 MB of RAM used for Storage and 187.07 MB RAM used for Programs. ANYTHING within either CAN be deleted to free up space. Some badly decided removals (most) will cripple Windows, some sit taking up huge amounts of RAM. Games and music preloaded in particular.
Removing anything via Crudscraper (nothing vital) IS GONE. Watch the Storage RAM available increases to validate.
ONLY a hard reset will make Crudscraped items reappear. Otherwise they ARE erased from current OS.
Use freeware Treesize to breakout every RAM MB into tree-view directory. The "bloat" IS in user's control done carefully or just auto-magically running Crudscraper.
ROM is NOT same as RAM.

If you know this, then why are you so wrong about everything else? Nothing in ROM can be deleted manually. It may disappear (as in the case of Manila mods that overwrite files, for instance), but it isn't actually deleted. The OS and some of the carrier addons are in ROM. Crud Scraper does not delete anything in ROM. All it does is delete the shortcuts (*.lnk files) and any parts of the program that are in Storage Memory, but the parts that are in ROM remain taking up space. The only way to remove something from ROM is to install a custom ROM that has had those items removed. Much of the stuff users want to get rid of, like the AT$T crap, is in ROM and can't be deleted.

RAM! RAM! RAM! is the topic. NOT ROM (READ-ONLY)! One CAN increase available RAM deleting what's been previously written to it. Period.
Crudscraper reclaims 40-50MB if you actually read ANYTHING about it.
