In that case either you're sending the shutdown command to the UPS at 
the wrong time (it should be near the bottom of the halt script, just 
before the system power-off command) or your database doesn't respond to 
a SIGTERM signal in a timely matter (it doesn't have enough time to 
proceed and it receives a SIGKILL before it has finished).

It can't. At the time you're looking for this file, the syslogd won't be 
running anymore, so you can't write to the logs anymore. This is normal.
