I encountered an issue with gnome-system-monitor that caused the cpu usage to goto 100%.
I had a bad behaving task that created about 10,000 zombie tasks. If I clicked on the system monitor applet, when it tried to launch gnome-system-monitor I never saw the GUI and the CPU spiked to 100%. I killed the process that created the zombies, and gnome-system-monitor started behaving normally for me.
If it's of any interest, Firefox created the zombies. I think an ill-behaving extension was trying to update itself and created them.
