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.

Quick Question on Pagepool

If you run lots of memory heavy software, is it better to run a LOWER pp, or higher? It was my thinking that a lower number, like 4, would allow more things to run well at the same time. I just read a comment that says the opposite; someone suggested a pagepool of 8 if you run lots of memory heavy stuff...I use GPS software that tends to take up a lot of ram, and I am just never sure which pagepool number to use for myself

The higher the page pool the faster your phone will be running apps, but then there is the balance between speed, and running out of ram.
The best idea is to try a 6meg PP, run as MUCH as you think you will at the time, MAX out your ram usage, and see if you have 2megs to spare, if so, then an 8meg page pool will speed things up.

I personally liked using 4MB PP when i was running GPS as GPS for sure needs a lot of RAM to keep it running. It also kelped me keep up with txt and stuff, as there was a bit more RAM available.

yeah, i found that on lots of roms, while running gps if i open a text message, it would shut down the gps and i'd have to launch it again, or IE, etc...that is most annoying

for sure IE will shut it down, as IE needs more RAM. But txt should not cause you any trouble. I gave up on GPS due to those RAM issues, so i went and bought a Magellan 1200

I have been using K's rom with a 6mb pp. And during work I leave excel and outlook open all the time, and will run gps and IE here and there, along with some other random programs, including adobe with some large pdf's, with no problems.
I have also been using sk tools, it comes with a "free ram" program that seems to help when memory starts getting low. But, if you have too many things open, it will sometimes shut one of them down (normally IE). But, I really don't have many issues. I also reboot the phone about once a day (In the morning).

iGO8 - Page Pool 4mb
- file system cache AUTO
- glyph 16kb
should be ok
TOMTOM 7 doesnt need so much memory but should be same as iGO

How to clean the most RAM in WinMo 6.5

I have just upgraded to WinMo 6.5 and, although, it runs pretty smoth, it eats up to much RAM. I have disabled push internet, opera staying in memory, etc, and it still uses (without anything else running) 41% of RAM. Starting and ending programs rushes up the RAM usage to above 50%. Applying RAM Sweep and/or cleanRAm does not bring back all the (dis)used RAM. Are there any other ways to clean as much RAM as possible? In WinMo 6.1 my average RAM usage was 35 to 38%.

you could try using Timor.8 rom.. has everything stock from european version.. has optimize for low usage of ram... smooth and stable, and after i use cleanram, i wait awhile for another use and everything seems to settle down and drops back down.. you should try it

hey I was wondering myself, how much total
Storage and Program rams do you have?
I am using the timor.8slim rom and I am having
Total: 184.41 MB
In Use: 103.30
Free: 81.11 MB
I am just wondering if the total is normal? I thought it had more?

Tilt 2 Memory usage

I recently upgraded from a Fuze to a Tilt 2 (AT&T). I am running the stock AT&T Tilt 2 Rom. I have applied the hot fixes on their site though.
It is the same processor as the Fuze yet it is much more responsive, I love that. But I have a question. Even when I am not running anything (other then the TouchFlo interface) it is hovering around 80% of program memory usage, and there is only ~40mb free.
The fuze had the same amount of memory, and in the stock rom it was only using ~40% of program memory.
I am monitoring this after reset, so I am not looking at memory leak.
Is this normal for everybody? Any idea what is running in the background to waste so much memory? The task manager (windows default) does not show anything else running.

HKLM\Software\HTC\ResProxy
"ShareMemSize"
Change this value to zero
I found this in this link if you want more info on it.

There's a couple of settings common to all models of the TouchPro2/Rhodium (which the Tilt2 is one of) that help to reduce the base memory footprint of running WM and Sense (aka TouchFLO3D). Cabs for them are attached below (SSK TP2 Dynamic Resource Proxy and NoPushInternet).
There's also a number of resident apps/programs that AT&T packs into their stock rom that are unnecessary and can be cleaned out. They won't make much difference in your available RAM (unless any of them get started and are running in the background), but cleaning them out can free up a significant amount of storage memory. There's a utility that's been built to help you clear them off, here's the link with info on it:

EDIT: The first cab I attached does the same thing as the registry entry vnb28 mentions above

The biggest memory saver is disabling Opera from running in the background on start up. This uses 8-10 megs or so it appears on my phone. There are lots or registry edits and cabs out there that will do this.

I was under the impression that was the net effect of the NoPushInternet cab I've been using (attached in my previous post)...I haven't used any other cabs for that purpose, and it doesn't load for me anymore.

Thanks guys! You are brilliant! That free'd up a bunch of memory (Share Memory trick). I am going to leave Opera running in BG for now because I use it a lot, but will remove it if need be later. I am staying around 50% usage right now, which should be plenty of free program memory.
And thanks sirphunkee, I was wanting to remove some of that crap (like stupid game demos) but could not. I tried to deleting the large exes but that was not allowed either.
My system is running great now thanks to help from these forums!
If there was only a way to get weather (no fancy animation) on home screen of Touchflo 2.1 !

[Q] Ram Leak?

Can someone clear up something im tryna figure out? The rhodium has 288 mb of ram right? I was wondering why my phone says max ram is 185 and only about 90 free ram left with all programs closed. On different roms it would say 136 free with all programs closed. In xandroid it would slowly decrease as if its leaking to nowhere even when i close all programs. Is this normal for android or does my windows build effect the ram in android?
To clarify my question, im asking why is it so low in winmo and is it normal? Also is it at a normal level in android and does winmo's reading of ram affect xandroid? Thanks

Nobody knows? Well could somebody tell me what their max ram says and is it normal? Mine says 186 with 90 free

I am using the stock AT&T rom from this past August. I show max ram as 187 and typically have about 92 megs after a soft reset. I have gotten it as high as a little over a hundred depending upon what I run at startup. That extra RAM under the 187 is being used by the OS and by HTC. Sense is a real memory hog but if you are at 90 I am guessing you have Sense turned off. The Start menu uses 10 mega itself.

Thank You! All I wanted to know lol. So mine is normal phew. I use titanium energy rom. Didn't like sense ui or touchflo3d
