As I said, I'm trying to learn.  I gather, then, that there's a way for 
the computers to know when they're running off of the UPS only and that 
they're set to shut themselves down when the main power's been off for a 
specified length of time so as to avoid completely discharging the UPS, 
or causing the problems you described?  If so, thank you for helping me 
learn; if not, feel free to correct me.

And, in any event, kernel panics while shutting down or rebooting are a 
bad thing.
