Not sure that's really the underlying problem. Depending on how they
killed the processes there's a slight chance for corruption, but more
likely they've got bad hardware.  Can they take their machine down for
testing?  memtest86+ is a good tool to get an idea if you've got a
good cpu mobo ram combo or not.

The last bit you included definitely looks like something's corrupted
in the database.
