- Solved
I'd created a post in the support forum but after doing more searches maybe I'm actually seeing a bug here. There is some background info here, but basically I'd been running rock solid for weeks with no problems. I started trying to use a Windows VM converted from a physical machine and pass my GTX 1050 Ti through. While that all appeared to work fine as well, now my Unraid server becomes non-responsive. Sometimes this happens late in the day, sometimes the next morning, but it is pretty consistent and I can't access the web GUI, ssh, and usually even the local display. I've run at least one pass of memtest and had 0 errors in that run as well.
I've attached a diagnostics zip here as well, but here's what caught my eye today:
