Hi,
It just happened again (it's happened twice this morning after happening 3
times last night) and I still had the serial console open, so got the
information it spat out when it died - if this is any use!
[note I also uninstalled telegraf last night]

https://www.openbsd.org/ddb.html describes the minimum info required in bug
reports. Insufficient info makes it difficult to find and fix bugs.
