My unraid has been crashing every once in a while for quite some time now. And when it does, it takes my entire home network down with it.

 

Back story: I always thought it was my ethernet switch that's failing, since each time unraid crashes, nothing connected to the switch is accessible, but everything else on my network is. I've been going back and forth with the manufacturer, where they were kind enough to send me 2 new units to try out, but after a while, it is still happening. Thinking the switch was a piece of trash, I switched to another manufacturer's switch, but odd enough, same thing is still happening.

 

So I decided to dig around my unraid a bit more by syncing the syslog to my USB. It crashed again last night, but this time it didn't take out my whole network, because I only have 1 ethernet connected to it at this time (probably crashing because of link aggregation).

 

Below is what I caught in the syslog, and also attached diagnostics of my server.

 

Any help would be greatly appreciated, thanks!

Would anyone be able to help with this?

I tried disabling C-State in my BIOS, but it still crashed last week.

 

Can someone provide any suggestions on where to look at? I'm at a total loss here.

 

If I'm missing anything, let me know and I'll try to provide more information.
