I've noticed the exact same behavior and I'd also say the system isn't 
going through it's normal shutdown routine.  I have upssched setup to 
e-mail me when events happen, and in the case where the system goes on 
battery I have a 300 sec timer start.  When that timer expires, it 
should e-mil me about the status.  In the system logs, I see that 
upssched starts the timer but before it goes off the system has been 
powered off.  I don't see an expiration in syslog nor receive an e-mail 
about the battery state.  I've tested the script so I know it will 
correctly send the e-mail.

I booted into windows and ran their UPS monitoring software and did the 
same test (pulled power) and I saw the battery drop and then stabilize 
but the system didn't power itself off.  I ran it on battery for about 
10 minutes or so with no problems so the issue isn't the UPS.  I'm 
guessing something is getting triggered in NUT somewhere that is telling 
the system to shutdown the UPS.  The system shutdown isn't graceful 
either as I see ext3 recovering on next bootup.  I have 4 items attached 
to the 4 battery backed up ports (not all monitoring the main system 
yet), and all of them were off (because the UPS was shut off) so it 
isn't just NUT shutting down its one system.  It shut off the whole UPS.

Unfortunately, I haven't been able to get much farther than that yet.
