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
"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):
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
Killing "wnck-applet" does the trick. One has to
confirm reloading of the usual applets of the
bottom "GNOME" panel. Afterwards, normal operation
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:
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:
If not, feel free to reopen and we can debug the problem.
