From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20051018 Epiphany/1.8.2 Description of problem: I frequently encounter a situation where the bottom "GNOME" panel does not respond anymore. CPU clock and CPU load go up to the maximum. The culprit is "wnck-applet" which keeps the CPU essentially 100% busy like in the following snippet of "top" output: "2675 test 25 0 46972 10m 8480 R 96.5 2.0 0:29.22 wnck-applet" Version-Release number of selected component (if applicable): How reproducible: Sometimes Steps to Reproduce: 1. Login to "GNOME" session. 2. Use the system ... Actual Results: The bottom "GNOME" panel does not respond anymore. CPU clock and CPU load go up to the maximum. Expected Results: The bottom "GNOME" panel should remain responsive without any anomaly. Additional info: Killing "wnck-applet" does the trick. One has to confirm reloading of the usual applets of the bottom "GNOME" panel. Afterwards, normal operation resumes.
Version is: "gnome-panel-2.12.1-7"
I have never seen this. Do you still see this issue with current rawhide ?
I haven't seen it for a couple of weeks now. So, I guess, it has been fixed in one of the "GNOME" 2.13.x snapshots.
I recently upgraded to FC 5 and I have also noticed this. It turns out to happen fairly regularly when launching on program in particular (Mathematica). Let me know if there's any info I can provide to help debug this issue.
For Mathematica, see the following: http://forums.wolfram.com/student-support/topics/10215
Right, I can definitely confirm that the issue appears after using the graphical frontend to "Mathematica" which is called "mathematica". Because I usually only deal with the command line executable "math", I hadn't observed the issue for a while and thought it was gone. However, it is still around for the current "libwnck-2.14.0-1".
I believe this got fixed in 2.14.1: http://bugzilla.gnome.org/show_bug.cgi?id=332493 If not, feel free to reopen and we can debug the problem.
