frequent "cleaning memory (low memory)" warnings

I've been receiving frequent "cleaning memory (low memory)" warnings recently.
I'm on a rooted RC33 and I have all my caches and my apps (both app and app-private) moved to my sdcard and that partition has TONS of space.
I do have a lot of apps installed, but most are not constantly running background-type apps/services.
What can I do to resolve this? I am happy to post the output of various diagnostic things if anyone has suggestions.
Thanks

moving apps to flash won't have any effect low mem has to do with low ram not flash.
do u have dxtop installed? the latest ver stays in memory which means less mem for other apps

Have you installed aHome? I noticed the low memory warning too for the first time last night. I think the only thing new I installed was aHome.

I also have dxTop and found this in the release notes. Maybe this is what caused the msg to pop up.
"More memory released when the phone gets low on memory."

I do, but I decided not to use it as it was really slow. It is still installed, but it never comes up (shouldn't even run) as I set dxTop to my default home app.

Interesting. Maybe my phone was running low on memory all along and it is just that now dxTop is report it to me visually

if you have dxTop go to the setting of dxTop > menu >> dxTop uncheck what it says disabel persistance.
it eats all ur memory.. uncheckign that will run a lil slower when returnign to home but will have more memory for other apps

Oh, ok, I'll try that. Thanks.
I'm also getting the "low space" icon, which makes no sense because I have tons of space (all apps/caches moved to sdcard).
Code:

busybox df -h

what conditions trigger the "low on space" indicator?
<moving this specific question to a new thread (http://forum.xda-developers.com/showthread.php?p=3450296#post3450296) as it is somewhat unrelated>

xDtop claims they fixed it in the latest version. Don't see the message anymore.

Low memory means low RAM, not low flash or storage space. Completely different things.

idk, it seems that the two users that showed their df -h command output have an awful lot of data being used, many of my apps run all the time and i am only using 19% rather than the 90 and 91 in the previous posts. i have dxtop installed and have had it for a while and have NEVER gotten this problem.

what *specific* conditions trigger the "low on space" indicator?
I'm confused. I have my apps and caches moved to my sdcard but I am still getting the "low on space" indicator. Which directories/filesystems are causing it to think it is low on space? Can anyone explain why it would say I am low on space under these circumstances?
This is how my device looks at the moment (and I am currently getting the "low on space" indicator):
Code:

I'm not sure... but this was my results. I have apps to sd too.

Hmm... I wonder if /data/data could/should be moved/symlinked as well...?
EDIT: Yeah, that seemed to help. The low space warning went away.

that folder grows pretty big.. now, im not sure if we are allow to move it to the sd? i moved mine.. have not gotten any problems errors yet.. but try movign it to your ext2 partition
Code:
busybox cp -a /data/dalvik-cache /system/sd/dalvik-cache
rm -rf /data/dalvik-cache
ln -s /system/sd/dalvik-cache /data/dalvik-cache
reboot
edit: wops did not read ur last post, wjhere u moved the whole data folder

this posting will be merged with your OLDER postings about the same thing.
Anymore X-posting or multiple thread openings about the same issue will be resulted to a closure of each thread and/or up to a temp ban.

Thanks for the tip -- I just did that (moved davlik-cache) and that seemed to help as well. I hope I'm all set for now.
Note to moderator: apologies for the violation of protocol. It won't happen again.

[Q] Where's the mount point for the root file system?

On my G1, I know that the internal flash memory is divided into several partitions used by the system. Running the busybox shell on a terminal emulator on the phone or through adb, I can run df and get the following:
Code:
Filesystem 1K-blocks Used Available Use% Mounted on
tmpfs 48852 0 48852 0% /dev
tmpfs 48852 0 48852 0% /mnt/asec
/dev/block/mtdblock3 92160 89048 3112 97% /system
/dev/block/mtdblock5 91904 77792 14112 85% /data
/dev/block/loop0 4096 4096 0 100% /system/xbin
/dev/block/mtdblock4 30720 1160 29560 4% /cache
/dev/block/vold/179:1
15541688 12742232 2799456 82% /mnt/sdcard
/dev/block/vold/179:1
15541688 12742232 2799456 82% /mnt/secure/asec
But strangely there's no mount point for /, the root file system. Yet there are lot of other files and directories directly in the root file system, like init scripts. Could anyone explain to me how this is? Is the root file system hidden somehow from df?

[Q] total memory space 00.0B

Hello,i have an unsoluble problem,my tablet pc 3q Surf TS1003T with android 4.0 (team DRH and antibyte kernel) do not calculate total memory space.Total memory space in settings is 00.0B,after every reboot files down in /mnt/sdcard automatically are removed and access rules of the folder /mnt/sdcard are nullified.
I reload partitions with the help of NVflash and used the various ROM,but it didn't yield results.
This are results of "df" comant in terminal emulator:
Code:

Reinstallation of a System App fails: not enough memory - but there's plenty of it

Hi
My Phone is rooted and uses Link2SD, but with the stock rom.
Recently I wanted to remove the album updates of my Sony Xperia M (Android 4.3). But not only the updates got removed, instead the whole app disappeared.
So I thought: strange, but I'll just reinstall it from the market. But then I got a not enough space error - but there are 1.5 GB left, and album has a size of 10mb.
Then I searched in filesystem for leftover files and found semcAlbum.apk and it's corresponding lib files (no dalvik cache files however). I made a backup and deleted them, then I tried to install semcAlbum. Same problem: not enough space.
But there is enough space - I tried to install another app with 50mb - no problem. So there probably must be an issue with leftover files, but I can't find any more of them in
system/app
data/app
data/app-lib
data/dalvik-cache
data/sdext2 +subfolders (link2sd)
data/local/tmp
data/data
So what can I do now?
Thanks in advance.
