I've seen the timers: heartbeat.conf has two 300 sec timers, upssched.cmd
looks
like what is often called upssched.conf and has a 660 sec timer.  So it looks as
if the heartbeat has worked once, after 10 min.

Do you have a file upssched.conf?

I would expect upssched.cmd (perhaps upssched-cmd) to contain a script.

It is consistently happening 14-15 minutes after starting. Please see attached
upssched-cmd and upssched.conf. I don't have a upssched.cmd. The binary
upssched is used.

If you speed up the heartbeat by reducing the timers in heartbeat.conf from 300 
to 150, and the timer in upssched.conf from 660 to 360, does the failure still 
occcur after 15 minutes?
