Hello, i'm a relatively new user to unRAID. I had my server running on unRAID 6.10.2 for about two months with no issues of stability or unexpected downtimes or reboots. I upgraded to 6.10.3 and sometime around since then, i've had intermittent freezes in the unRAID OS. The machine completely stops responding to all network services including basic pings, and the console doesn't respond to the keyboard and mouse.

 

i set up a remote syslog after the last freeze, and it ran for about a week before freezing again. i've attached the full log, and here are the final lines before the freeze that look potentially relevant:

i also attached my server's diagnostics. Let me know if there's any more information i can provide!

Unlikely that's the problem, but it does show you're using a SATA port multiplier, and those are not recommended, though usually they cause disk related issues, not server crashing.
