If you suspect hardware problems or critical timing, you could
propably (additional to Jerry's ideas) vary voltages as well
as the temperature of your board. If you see any correlation
to the number of crashes you will have a hardware problem for sure.

I've had a problem with some flash memory on a broken 8548 board
last week which was working more reliable on higher
temperatures... @:-]
