Nut upsuser - Mar 2024 - Heartbeat timer failure 15 minutes after startup

I have 3 Raspberry Pi NUT 2.8.1 systems running PI OS. (Debian 11 and 12)

All three systems have a heartbeat-timer failure approximately 15 minutes after
starting NUT. No subsequent failures. Any ideas on what is happening?

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.
