After reviewing the bug reports I tried the easy solution: 
removing power from the computer for 5 minutes - not just 
powering down, but shutting down and unplugging.  Worked just 
fine - APCUPSD died sometime more than an hour after startup and 
less than 24 hours but was manually restarted without problem.
