I've seen reboots like this. I don't worry about it if it's a single case. If 
it happens more frequently and around the same time, check your cron and 
periodic scripts. Run them by hand when you're physically at the machine.

If that doesn't solve it, the only other option may be to get up at 4am in the 
morning to catch that rodent nibbling your power cable.

    and never get to the software part.
