Version:           unspecified (using Devel) 
OS:                Linux

After some time, plasma-desktop ate 950 MB of memory.

Here is the core dump of it: http://www.morrohun.hu/temp/plasma-core.7z

Here is its backtrace from that state:

Reproducible: Didn't try




OS: Linux (x86_64) release 2.6.31.12-0.2-desktop
Compiler: gcc

Comment 1 winnfield 2010-06-17 11:35:50 UTC

Can confirm. After having KDE running through a whole night plasma-desktop ate over 400 MB of memory. Running for the rest of the day increased the consumption to 1,5 GB.

Using:
Linux 2.6.33-ARCH (x86)
KDE 4.5 Beta2

Comment 2 Vlad Adamenko 2010-06-27 11:24:22 UTC

I can confirm, that on my notebook, process "plasma-desktop" ate over 1.2G of RAM a day. I've restart that process and I have same situation next morning.

Comment 3 Michael Meier 2010-07-05 15:54:23 UTC

I had this problem with 4.4.85. Seems to be gone with 4.4.90.

Comment 4 Vovochka 2010-08-11 05:57:17 UTC

It's 4.5.0 release and plasma is really greedy for memory. In have an hour it's ate over 200 mb.

Unbelievable that it's a release.

Comment 5 Tomas Thiemel 2010-09-20 10:41:54 UTC

OS: Arch Linux 64bit
uname: Linux uw000459 2.6.34-ARCH #1 SMP PREEMPT Mon Jul 5 22:12:11 CEST 2010 x86_64 Intel(R) Core(TM)2 CPU 6400 @ 2.13GHz GenuineIntel GNU/Linux
Package version: kdemod-core/kdemod-kdebase 4.5.1-1

Memory leak: after some time starts to consume cca 0.5MB per second until SWAP is 100% filled or until I kill "kdinit4: plasma-desktop" process...

Comment 7 John Paul 2011-11-02 14:46:05 UTC

KDE 4.6.00
OpenSUSE 11.4
uname: Linux dhcppc0 2.6.37.6-0.7-desktop #1 SMP PREEMPT 2011-07-21 02:17:24 +0200 x86_64 x86_64 x86_64 GNU/Linux

I had the same problem: plasma-desktop using insane amounts of memory, over 200MB after a few hours.

I had, among others, the Now Playing widget and RSI break widget on my desktop. I removed both and the problem hasn't reoccurred since.

If you're using any of these widgets, please try removing them and report the results, if any.

Comment 9 Unknown 2011-12-23 16:31:02 UTC

In this case can I delete the 150 MB core file from its external location?

Comment 10 Unknown 2011-12-26 21:09:09 UTC

Since I got no answer whether I can delete the core dump, and there was no advancement resolving this bug since one and a half year, I removed the uploaded core dump.
