Description Marius Bjørnstad 2012-09-03 17:34:46 UTC 
kded4 memory usage slowly increases. 

It has been killed once by the out of memory killer, then the system tray icons were no longer hidden, and the Sleep and Hibernate options were no longer in the system menu. Logging out and back in restored everything to its normal state.

I am a heavy user of the "Sleep" function, and this bug could be related to a problem with Sleep. A few times there is no password prompt when waking up from Sleep mode.

After 3 days it uses 1.1 GB. From "ps auxww":
fa2k     29920  0.0  6.9 3588052 1149936 ?     Sl   Aug31   1:19 kded4


Reproducible: Always

Steps to Reproduce:
1. Leave a session running for a long time
2. Maybe: use the Sleep (suspend to RAM) function
Actual Results:  
kded4 memory use slowly increases in small increments. Appears to be correlated with opening new windows.


Work-around: Log out and back in again
Comment 1 Christoph Feck 2012-09-03 19:57:03 UTC 
Please check which kded module is responsible. For more information, see http://kdepepo.wordpress.com/2011/05/11/troubleshooting-kded4-bugs/
Comment 2 Marius Bjørnstad 2012-09-03 20:58:11 UTC 
I get about 30 messages per second like the following in the kernel log
(dmesg). Maybe that is related to the memory use.

[426199.823707] ehci_hcd 0000:00:12.2: port 3 resume error -110

The messages started when I connected a bad USB device. Sorry I didn't
think of this before. I can't reboot now, but I'll do it in a couple of
days and report if it still happens.

I tried to start and stop "Power Management", and about 1 minute later,
I got a segmentation fault. The only message was "Application: KDE
Daemon (kded4), signal: Segmentation fault" ("The generated crash
information is not useful"). Now kded4 quit and was restarted, and the
memory usage is low again ~50 MB, but it increases at about 1 MB per 20 min.

Comment 3 Marius Bjørnstad 2012-09-11 16:34:04 UTC 
It still happens, and the memory remains high even when I stop various services. It's somewhat difficult to disable services and log in, because it takes hours to see if it's actually leaking. I will update this bug if I find anything.
Comment 4 Laurent Bonnaud 2012-10-28 14:44:33 UTC 
I am also seeing this bug in Kubuntu quantal with KDE 4.9.2.  Here is the kded memory usage I see in a KDE session that has been running for 7 days:

$ ps aux |grep kded
bonnaud   3377  0.0 15.3 1185376 620392 ?      Sl   Oct20   3:23 kdeinit4: kded4 [kdeinit]
Comment 5 Christoph Feck 2012-10-28 14:56:59 UTC 
Please read comment #1. Without the information, which module is responsible, we cannot do anything. Start with disabling the power management related modules (see bug 294497, bug 271934).

valgrind log

I ran kded with valgrind.  Many memory leaks are reported.  The main one is:

==4846== 4,364,285 bytes in 136,872 blocks are possibly lost in loss record 9,681 of 9,681

Comment 7 Christoph Feck 2012-11-07 22:59:17 UTC 
Laurent, thanks for the valgrind log. Could you increase the number of callers visible, so that we can see which KDE component calls the glib stuff? E.g. valgrind --num-callers=30 (or more, if we cannot see the caller).

For more information, see http://people.gnome.org/~newren/tutorials/developing-with-gnome/html/ch03s03.html
Comment 8 Vangelis 2012-11-11 15:41:54 UTC 
I face the same very annoying problem. After a few hours of work, kded4 consumes more than 2GB memory itself.

Is it correct if I run the valgrind command like this and provide the log file?

valgrind -v --leak-check=full --num-callers=50 kdeinit4 kded4 >& kded4-valgrind.log
Comment 9 Jekyll Wu 2013-01-02 11:23:27 UTC 
Laurent,  I think another suspect in your valigrind log is  kded_notificationhelper.so
Comment 10 Christoph Feck 2013-01-12 02:55:31 UTC 
Was anyone able to pinpoint the kded module responsible for the leak?
Comment 11 Vangelis 2013-02-14 18:40:48 UTC 
(In reply to comment #10)
> Was anyone able to pinpoint the kded module responsible for the leak?

Power management is the culprit for me.
Already posted this in this bug: https://bugs.kde.org/show_bug.cgi?id=271934
Comment 12 Marius Bjørnstad 2013-02-15 11:08:07 UTC 
Sorry, I meant to reply but forgot. I upgraded my hardware and I'm not seeing the bug any more. Perfectly flat memory usage. I don't know if it's the new H/W or 4.10 that fixed it, so I can't be of much help. It did seem that the suspend/resume process sometimes didn't fully complete on my old hardware though.

valgrind log from kded4

my desktop computer  running Fedora 17 x86_64 kde 4.10 (happened with kde 4.9.x too) have the kded4 memory leak

if I disable the Power Management module the leaks stops

in my case the leaks happens in a desktop computer, I have a netbook Fedora 17 kde 4.9.2 and it don't have any memory leaks

I tried to run kded4 under valgrind with the following command line

valgrind -v --leak-check=full --trace-children=yes --num-callers=50 kded4 >& /tmp/kded4-valgrind

thanks, 

gabrielo

Comment 15 Jiri Slaby 2013-03-10 15:02:07 UTC 
The only thing we have in common is the vendor (intel). Other than that I see no intersection. FWIW I see the issue with 4.10.0.
Comment 16 Jiri Slaby 2013-03-10 16:07:19 UTC 
Ok, so I created two separate bugs for the issues valgrind has found here: bug 316473, bug 316473.

Do you have systemd version > 197?

I had the same memory leak issue with 4.9.x as well on my laptop
Comment 19 Gabriel Ramirez 2013-03-11 19:05:53 UTC 
Mi machine is intel  core 2duo, Fedora 17 x86_64 but it's a desktop

the machine can sleep and hibernate correctly, 
also put's to sleep the monitor correctly via dvi and in the past via vga

my problem in my case is which kded4 grows the resident memory and consumes virtual memory too (swap) until killed and restarting kded4 and the cycle begin again

the grow in memory happens without sleeping or hibernate the machine

the problem happened with kde 4.9.x 4.10 and currently happen with 4.10.1

I only restart after 7 or more days of uptime sometimes 40 days 
I have to kill kded4 several times but besides that the os and kde worked perfectly

and I have a netbook Fedora 17 i686 kde 4.9.2 and now 4.10.1 and it don't have the problem and it sleep, hibernates and turn off the lcd correctly.

thanks, 

gabrielo
Comment 20 Andrew 2013-04-16 14:03:51 UTC 
It leaks for me too.
I'm on up to date Kubuntu 12.04 64 bit with KDE 4.10.2 from backports.
After disabling power management memory usage remains steady.
Comment 21 Rex Dieter 2013-05-07 23:01:49 UTC 
May be a dup of bug #271934
Comment 22 Bill McGonigle 2013-12-10 16:32:45 UTC 
Disabling power management also seems to work for me.  Previously, kded4 was at 3GB resident, 12GB virtual(!).  I was happily able to cleanly kill it with HUP and restart it as a regular background process without losing my session.

This is an AMD A6-3650 based desktop (MSI board).
