Description Alexander Runge 2006-01-11 04:11:52 UTC

Description: After upgrading from kdebase-3.5.0 to 3.5.0-r1 these days kdesktop   started leaking  memory. After KDE initilization kdesktop consumes about 20MB of RAM after 12h it consumes about 50MB and after 2 days I had it at 170MB (according to top)!
I used kdebase-3.5.0 for several weeks without this specific problem.
I can manually kill and launch kdesktop without restarting the whole KDE session, which frees the allocated memory, but the behaviour is always the same.

Reproducible: always (at least on my system).

My kdestop has been running 7 days:

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
caleb     6119  0.0  2.6  34664 24256 ?        S    Jan04   0:19 kdesktop

I'd say something else is going on.  Are you sure it's a leak?  You can always run it through valgrind and see what it says.

Comment 3 Alexander Runge 2006-01-11 05:16:07 UTC

Caleb, I attached a valgrind log as you suggested. Unfortunately I can't make any sense of it... I'm not much of a programmer...


Alex!!

Comment 4 Uli Schlachter 2006-01-27 08:04:22 UTC

The log just says there is no memleak.

Comment 5 Alexander Runge 2006-01-29 00:57:10 UTC

Hmm, still the problem remains... what else could it be. This is really annoying...


Alex!!!

Alexander, does turning off wallpapers help you?

Looks good. I set the KDE background to plain color and made these ps 
snapshots every 15 minutes:

So problem lies within kdesktop's caching routine, right!?
Now, how can I live without my wallpapers ;-P
Anyway, thanks for the hint, Alex!!!
