So my FreeBSD 12.1-RELEASE-p8 system keeps going unresponsive, with no specific error I can see in the logs (unless I'm missing something). Even the console output, I get nothing. If I have a USB keyboard plugged in, doesn't respond to input. If I plug one in after it goes non-responsive it doesn't get connected/powered up (spare keyboard, has backlight keys, keys don't light up).
I'm on a Ryzen 1700X, 32GB RAM, Intel PRO/1000 NIC, run bhyve (via vm-churchers) with a few VMs such as Ubiquiti Controller, pihole, Home-Assistant, Samba for file shares, and such. When I notice it goes unresponsive (via SSH dropping, can't connect to shares, etc), often there's errors similar to below, although sometimes it's some random sendmail lines. I zroot, and a 8 disk RAIDZ2 array. I still have plenty of available space on zroot and my storage pool.
Anyone have any thoughts on things to check, any debug/logging I could enable which might help? Any places to check other then /var/log? I'm at my wits end, just don't understand what might be happening. I can't think of anything particular that might have changed, and it's definitely at random. Sometimes weeks will go by, sometimes less than 24hrs.
