Processors at 100%, server unresponsive

[Beller0ph1]

I've had this happen a few times with my server build.

The server dashboard shows 100% on all 4 cores of my CPU, the web GUI is unresponsive, and I can't access my shares from Windows or any of my Docker containers.

I can log into the server via SSH and WinSCP to do a few things, but most commands hang.

I run htop in SSH and only see 1 core at 100%, which doesn't match the web GUI.

I couldn't run "diagnostics" from the SSH command line; it would hang for a long time.

I can't run "reboot" from the command line.

I did capture the syslog before doing a hard reboot, and ran a diagnostics after.  I hope you can make some sense of my logs.

I have a number of CRC errors on the Cache drives, but I think this comes from the AMD/Samsung Evo compatibility issues.  I have a new controller coming later this week instead of running them off the motherboard.

 

Setup:

Mobo: Gigabyte GA-MA785G-UD3H

Processor: AMD Athlon II X4 630

RAM: 4 x 2GB sticks

Parity: 1 x 8 TB Seagate Ironwolf NAS

Array: 1 x 8 TB WD Red NAS Plus

Cache pool: 2 x Samsung 860 EVO 500 GB

 

Syslog before hard reboot:

Thanks in advance!  I really like Unraid...when it's not crashed or run a parity check.
