It might be a good idea to turn off the screen saver for the console if
you do this.  If the crash happened after the screen saver became
active, you might see nothing but a blank screen.  Guess how I know
... :)

Other than that, I'd wait and see if it happens again.  If there appears
to be any sort of regularity to the crashes (like every 45 days), I'd
try to find out what is being started every 45 days.


Hmm ... I'm finding the messages about loosing contact to the UPS
suspicious.  I used nut quite a while with an USB connection, and no
matter what load I put on the CPU, I never noticed any such messages.
Do you see a correlation between CPU load and these messages?
