I do not think it is a memory issue because this box has 2 gigs of
memory in it.  Up until half a year ago, I was using 1 gig with no
issues.  I suppose one of the memory sticks could have gone bad.  What
should I be looking for in top (which does show X and mythfrontend
using most of the CPU when this happens).
