updating to KDE 4.7 -> memory is leaking

irrlicht · 2011-07-31 14:30:02

Hello!

After update to KDE 4.7 my system got a memory leak.

Linux cassiopeia 2.6.39-ARCH #1 SMP PREEMPT Sat Jul 9 14:57:41 CEST 2011 x86_64 Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz GenuineIntel GNU/Linux

16:20:34 up  4:57,  2 users,  load average: 3.18, 2.01, 1.01

root # free                                                                                                       
             total       used       free     shared    buffers     cached                                         
Mem:       4058660    2416460    1642200          0       1316     254536

Swap:      4198396          0    4198396

As you can see, after 5 hours of uptime, the memory usage increased from ~400Mb to 2,5GB.
After ca. 8 hours system go upon 3GB and begins to swap aggressively. How i can determine which component causes the leak?

Here is ps aux output:

ty in advance.

Similar thing has happened on my machine, but suddenly stopped. Please tell me what graphics card are you using, and what drivers, mesa version, etc. Also, did you compiled kde-workspace to use Open GL ES?

I upgraded to KDE 4.7 too and i don't recognize any leaks or other failures so far.

you can use ksysguard and look for the library causing the leak. If it's X leaking you will need root privileges to see what leaks what)

Other handy tools are top/htop , xrestop (in case of a pixmap leak like nvidia/kwin combo loves to do) and pmap (with pmap -d `pidof <program>` )

Also what's your GPU / driver and what kwin/compositing rendering engine is in your Desktop effects > Advanced (Xrender or openGL)
Also are you using the QT default rendering engine (native Xrender) or raster or opengl (not the same as kwin's)

I've experienced another leak, after a while it hasn't happened. So far ksysguard, top/htop, xrestop haven't been of any help (with pmap I even don't know what to look for), so I still don't know what causes leakage.

Going to init 1 also doesn't help, leaked memory isn't released, so the problem must have been somewhere in hardware drivers (such as mesa).

There's a thread here on Strigi and Nepomuk leaking.

What processes are using too much memory ?

Demon · 2011-08-01 19:09:17

oldpond, I don't use that c*ap, so I have it disabled.

ChoK, If I knew, I would have been solved the problem already.

I think that 64-bit flashplugin is the problem! At least here...

Arch Linux
