The errors you posted really look like hardware problems.  Hopefully
they'll be easy to isolate.  Check the CPU fan and see if it's spinning
and not making noises (once you've heard a dying fan, you'll know
exactly what to look for).  That's what bit me most recently.  Grab a
copy of memtest86 (any search engine will find it for you...IIRC it's
hosted at sgi.com).

The machine is probably dying during the nightly cron jobs because they
work it relatively hard.  updatedb, for example, will thrash the disk
pretty hard and use a bit of CPU as it updates the locate database.  It
also uses quite a bit of memory, so faulty memory could cause the kernel
to die when it tries paging.

If that doesn't help, then you're in for a bit of work, because further
problems tend to be tough to isolate.  Make sure all the cables are
plugged in firmly (internal cables, I mean).  If you have spare parts,
try swapping things like disks, CPUs, and power supplies.  It's also
possible that you've got a bad motherboard.

Good luck.
