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.
