When you say reboot do you mean shutdown/reboot or 'reset'/reboot. If it
is the second case you can have a main power problem or earth problem. I
have seen systems rebooting themself with 'spike' on the main supply or
when connected a Serial cable with earth problem or even static
electricity when someone touch the server.
Now if it is the first case. Do you have programs or deamons which can
shutdown the system (like ups software), may be someone can run them
without knowing it or a program thinks it needs to do so. You can have
some Hw/Sw problem at driver level when your system access Hw at the
same time for 'a' job. ( I had problem with a Bt ISDN card. We had to
buy one from another make, since every thing is OK, of course it was
under windoze which mean no error log at all just crash/reboot).
