This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle. Changing version to '12'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping If this happens again, what would be useful would be A) sampling multiple times with continue then hitting control-c until it is doing something other than the above (which is just waiting in the mainloop) B) if that doesn't work, then the a short snippet of running 'strace' on the process C) The output of ls -l /proc/<metacity pid>/fd I can't reproduce this any more, so no point in keeping it open. Probably one of the updates fixed it.

Created attachment 365027 [details] full gdb log Description of problem: I left my gnome session running overnight and all I found in the morning was the login screen again (=must have crashed, I'll try to report that too, but there is nothing interesting in the logs). I logged in again and found metacity using 100% cpu. A backtrace of the running process shows: (gdb) thread apply all bt Thread 1 (Thread 0x7f3fc1f45800 (LWP 21756)): #0 0x0000003b4dcd7fa8 in __poll (fds=0xf396b0, nfds=7, timeout=<value optimized out>) at ../sysdeps/unix/sysv/linux/poll.c:83 #1 0x0000003b4f43c9fc in g_main_context_poll (n_fds=<value optimized out>, fds=<value optimized out>, priority=<value optimized out>, timeout=<value optimized out>, context=<value optimized out>) at gmain.c:2904 #2 g_main_context_iterate (n_fds=<value optimized out>, fds=<value optimized out>, priority=<value optimized out>, timeout=<value optimized out>, context=<value optimized out>) at gmain.c:2586 #3 0x0000003b4f43d065 in IA__g_main_loop_run (loop=0xe53080) at gmain.c:2799 #4 0x000000000042b30e in main (argc=1, argv=0x7fff1e2f63a8) at core/main.c:599 (gdb) q Version-Release number of selected component (if applicable): metacity-2.28.0-1.fc12.x86_64 How reproducible: Unknown, it happened the first time.
