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.

Comment 2 Christian 2009-11-03 21:26:33 UTC
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.
Comment 3 Christian 2009-11-03 22:25:24 UTC
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.
Comment 4 André Klapper 2011-08-24 20:47:51 UTC
Is this still an issue in a recent version, such as 3.0 or 2.32, or can this be
closed as OBSOLETE?
