This is my first post here. I hope I am addressing this in the right section (moderator, please let me know where to put this, in case this section is incorrect). 

 

I am running Unraid 7.0 on a Gigabyte X570 UD motherboard and 48GB of memory, CPU Ryzen 5800X, plus an Nvidia 2060 super video card. 

I have a few Docker images (Plex, JellyFin, ..) and a few plugins running. The motherboard is built in a case with 9 fans, including the fans of the CPU water cooling. 

 

Unraid seems to halt after a few hours uptime. Tonight I was monitoring the CPU and it struck me that 1 thread (core if you will) was stuck at 100%, a few minutes later two threads followed to be stuck at 100% and then it looked like Unraid froze. All I can do is hard-power down the PC and boot up again.

 

Would any of you have any suggestions on where to start looking? I will check if I have the latest BIOS for the motherboard (don't expect anything here though) and will search for and go over logfiles. 

 

Thanks in advance,

Thanks! I'll give this a shot. 

Sorry to say, but my CPU locked up even after setting the BIOS as mentioned in your reply. 

It seems like the CPU locks up after I copy data from an Unraid drive to another (Unraid) drive. I have backed up the data and will try the XFS file system instead of ZFS. 

I could also revert to firmware 6.12.13, or do you @trurlexpect this to be pointless? 

Attach Diagnostics to your NEXT post in this thread.

 

Setup syslog server.

Here's the diagnostics file. 

I am setting up the syslog server now. 

Cut: ---- The Syslog server is set up and running. I am storing the syslog remotely on my Proxmox server.

syslog set up

@trurl

I noticed a wrong setup of one of the drives. The mover could not move the files on the cache drive to the HDD because I had incidentally excluded both drives where I wanted to exclude only one. I don't expect this could lead to the CPU locking up. I'll leave the Unraid server running and if the CPU locks up, I will provide the syslog on the remote server. 

 

 

I have installed a 5900x processor and a water cooler instead of an air cooler. Since then, I haven't experienced any CPU lockups.

Thank you for all your help! @trurl

The “cpu locking up” was likely due to IOWAIT which is because you were probably moving a volume of data from cache to your array. 
 

IOWAIT is basically the CPU waiting on the disk activity to stop so I can resume its other processes.

Something to look out for is if you ever notice the CPU load on the dashboard maxing out but the temps stay near idle cpu levels. It’s probably IOWAIT. The CPU logs IOWAIT as load but really it’s just “waiting”

 

or you might just be running out of RAM
