OpenBSD 6.8 GENERIC#5 i386
One of my systems rebooted at 03:01 local time today. I've seen kernel
panics and bad hardware but I've never seen OpenBSD "just reboot" by
itself, ever.
There's no cron job that would do this. last(1) is no help; it shows the
reboot command but not the shutdown that preceded it:
root@ns ~ 4# last -f /var/log/wtmp.0
reboot ~ Sat Mar 27 03:01
root ttyp0 192.168.0.132 Wed Mar 24 11:23 - 11:23
(00:00)
wtmp.0 begins Wed Mar 24 11:23 2021
root@ns ~ 5# last -f /var/log/wtmp.1
root ttyp0 192.168.0.132 Tue Mar 16 21:30 - 21:30
(00:00)
root ttyp0 75.82.86.131 Tue Mar 16 13:14 - 21:30

root ttyp0 75.82.86.131 Sun Mar 14 21:20 - 21:29

The date gaps seem odd. I've ssh'd into this system multiple times
between March 16-27. I don't see other signs of trouble in /var/log.
I could use some help in looking for evidence of foul play, or "just" a
hardware or software problem.
Thanks in advance for further troubleshooting clues.

What kind of a machine is it running on? I remember having reboot
problems on certain HP and Supermicro servers with hardware watchdogs.
