Hi all, ive been having this issue with unraid freezing every night and i am unable to access the UI. I know the unraid server is freezed as my VMs all get shut down.

Below is my log that i kept and found some hardware issue raised. Is this an issue with my motherboard?

Since you have multiple RAM sticks, try using the server with just one pair, if the same try with the other one, that will basically rule out bad RAM, other possibility is the CPU, since it's a 13700K, could be the Intel 13/14 issue, make sure the BIOS is up-to-date, that can sometimes help, as long as the CPU if not too far gone.

Thank you, i changed out the motherboard and updated the BIOS. Apparently it has been running fine ever since without the those errors in the log anymore.
