I will give that a try and see if I can cause it to happen again.

This same thing with the same errors has been happening to me. The mover triggers or I manually run it and rsync goes haywire and uses all of the CPU on the box (or close to). Then the OOM thread reaper starts killing off threads and eventually all shares disappear, the WebUI slows to a complete crawl and everything connected to the array gets IO errors. I caught it in the act today and attempted to run diagnostics while it was happening but the diagnostics script kept getting killed by the system. I was able to run a 'killall rsync' and everything became responsive again and was able to complete a diagnostics that I have attached for inspection. I am just getting started with unraid, having moved from freenas for the flexibility but this is going to make me move back in short order. I have disabled the cache completely, so mover shouldn't get me again, hopefully. newnas-diagnostics-20171024-0938.zip
