Description

I've seen this twice while trying to start up gnome desktop. Once
on a system built Sept 6, and again today after updating on Sept 21:

I suspect that something about my x11/gnome environment may be running
the system out of memory, but I'm not sure. I can put the dump files
on leaf if you want.
