Well, I wish I knew more about this stuff.  I was copying about 150MB
from one partition to another and everything started working again.  Is
there a feature of the vm that will clear all stuff from memory if a
process needs a bunch of memory or something?  I am assuming that for
some reason the kernel could not allocate the memory that moz and
up2date needed even though free showed memory available.  I will keep an
eye on this but since I can't easily replicate it, I will wait to file a
bug.  I cannot find anything in bugzilla that sounds like this issue. 
Has anyone else seen anything similar?
