--- Comment #16 from Jim Pirzyk <pirzyk@FreeBSD.org> ---
So I am seeing this also on a Virtual Machine since I upgraded to 13.1 (from
12.3 I believe).  It happens mostly when the machine is under load for some
reason (backups is a common culprit but not always).  I will note the machi=
ne
is starved of memory (2GB) and is swapping most of the time, to an encrypted
partition using GBE.  ZFS is not involved in swap (but is for the filesyste=
m).

A hard reset brings the machine back to life for several hours to multiple
days.  Very random.  Have not yet found steps to force it to happen.
