Core file? Stack backtrace?

I believe that's effectively the time of the last checkpoint. If the
system was idle between 5:30 and 10:15 or so then there's nothing very
surprising there. Tell us about the core dump.

Define "crash". Again, stack backtraces would be useful.
FWIW, a lot of the reports of instability we've seen recently have
traced to hardware problems. How confident are you of this hardware?
