X11 using up resources?

I'm running RH WS v3, its up to date with patches. Occassionally, I'll
have a few users logged in to it, some running VNC, maybe someone logged
in from the console.

Every once in a while I'll notice the load average on the machine go up
to 8.xx to 12.xx. When I run top to see what is running, I usually see
X taking up 99% of the CPU (see below).

I can't figure out why. The only thing I can think of is something with
someone's vnc session is causing this, but don't know what. I've
resorted to rebooting the machine to fix it, but I've had to reboot the
machine several times now. Has anyone seen this before or know where to
start looking for the cause?
