gnome-panel hangs with almost 100% CPU usage
Last modified: 2011-12-26 12:33:44 UTC
Created attachment 146812 [details] backtrace, strace and xsession-errors In irregular intervals gnome-panel takes almost 100% of cpu usage and almost freezes, i.e. there is a lot of hard-disk i/o, the cpu is heavilly buisy and if you click on an applet on the panel you get a response after some time (exceptionally the calendar app, there's no response). If you kill the process, it will be replaced by a new gnome-panel process, which has the same behaviour. I restarted gdm and after logging in there was the same behaviour. _Sometimes_ a reboot is helpfull. I wil attach an archive with an strace and a backtrace of gnome-panel. I use ubuntu 9.10 64bit amd. Moreover I use the proprietary fglrx drivers. $ apt-cache policy gnome-panel gnome-panel: Installiert: 1:2.28.0-0ubuntu6 Kandidat: 1:2.28.0-0ubuntu6 Versions-Tabelle: *** 1:2.28.0-0ubuntu6 0 500 http://de.archive.ubuntu.com karmic/main Packages 100 /var/lib/dpkg/status ProblemType: Bug Architecture: amd64 Date: Tue Nov 3 07:18:03 2009 DistroRelease: Ubuntu 9.10 NonfreeKernelModules: fglrx Package: gnome-panel 1:2.28.0-0ubuntu6 ProcEnviron: LANG=de_DE.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 2.6.31-14.48-generic SourcePackage: gnome-panel Uname: Linux 2.6.31-14-generic x86_64
this bug is also filed in the launchpad bugtracking system of ubuntu: https://bugs.launchpad.net/ubuntu/+source/gnome-panel/+bug/472245
No the bug can be reproduced (not in irregular intervals gnome-panel is hanging but on every login). I tried to delete the upper default panel (the one with the program menu, the calender app and so on). After the deletion cpu was on idle. Next I tried to add a panel. To this I added the programm menu app and gnome-panel once again took almost 100% cpu-usage. So it maybe has something to do with an error in the menu app. I also tried to empty the directory /etc/xdg/menus but with no success.
After I created a new panel as described above, I recognised that nautilus took loads of cpu time. Moreover I recognised a process ntfs-3g although no ntfs-volume was mounted. I looked into the /etc/fstab and there was an entry which should mount a ntfs partition. After removing this entry my system seems to run stable.
Is this still an issue in a recent version, such as 3.0 or 2.32, or can this be closed as OBSOLETE?
