My system is stable for weeks at a time, probably months.
But reboots after doing a specific task for about 30 minutes (GPU deep learning).
Unrelated to this task, but about the same time as the reboot I noticed
tail -f apcupsd.events
2022-02-24 11:41:49 -0600 apcupsd exiting, signal 15
2022-02-24 11:41:49 -0600 apcupsd shutdown succeeded
2022-02-24 11:54:32 -0600 apcupsd 3.14.14 (31 May 2016) debian startup succeeded
Does this say that something killed apcupsd ?
In the /var/log/kern.log I have at this time

What does "rfkill: input handler" mean?
Any other places to look to get a hint ask why my system crashes?
I recently upgraded to 20.04 from 18.04.
