Good evening

Hopefully I can get some help on this forum. My unraid started freezing randomly. Sometimes it happens when starting arraing and sometimes my Server runs 3-5 days without any issues.
I have tried a few things :

1. Recreated Cache Pools

2. Reinstalled my Unraid on flash

3. Recreated all my docker containers

4. Swopped memory

I have attached my syslog file and diagnostics

syslog (1) marais-homelab-diagnostics-20251102-2035.zip

Thanks in Advance

Syslog appears to be right after a reboot. Was the server crashed at that time?

I did reboot the system and then copied the syslog. Should I attach one without restarting the server?

The normal syslog starts over after every boot, enable the syslog server and post that after it happens again.

syslog-previous

Thanks I have uploaded the new file after crashing and before rebooting.

There are some ATA errors logged with parity. It is unlikely that will be the reason for the crash, but you should still check/replace cables.

For the crash, I see you have a 13600K, so possibly the Intel 13/14 gen issue, but if you have multiple sticks try using the server with just one, if the same try with a different one, that will basically rule out bad RAM.

Thank you very much
Its funny as my Server is running fine if I dont Start the array. The moment I start the array it Freezes at some stage.
I am busy running Smart Tests on all the drives now.

I did test the ram modules 1 by 1 at a time but the freezing continued.

Will swop te sata cables and if still happening I will try and get the CPU swopped out.

Thank you for the assistance

I replaced cpu. They sent me a 14600K back but I am still experiencing the issue.

Do you have any other ideas?

Syslog-previous only covers 1 minute of uptime; does that include a crash?

That includes crash, The moment I try to start array it crashes. I did let it idle now for a while without trying to start up the array. Then started the array and it crashedUploading Attachment...Uploading Attachment...

Don't see anything relevant logged. Does it start in maintenance mode?

Yes it does

What I found is when I disable docker it also starts the array without issues

That suggests an issue with a container, if they are set to auto-start, you can delete the Docker image and recreate it, then restore one or a few containers at a time and retest:

https://docs.unraid.net/unraid-os/troubleshooting/common-issues/docker-troubleshooting/#re-creating-the-docker-image-file

Then:

https://docs.unraid.net/unraid-os/troubleshooting/common-issues/docker-troubleshooting/#reinstalling-docker-applications

Also see below if you have any custom docker networks:

https://docs.unraid.net/unraid-os/troubleshooting/common-issues/docker-troubleshooting/#restoring-docker-custom-networks

Can the errors in this log be because of a bad Disk?

That looks more like a power/connection issue with that device; it should not crash the server, but it can appear hung for some time due to the timeouts, try replacing the cables.

Thanks, I will troubleshoot a bit further. Deleted the Docker Vdisk now and its already more stable. Will start installing all the dockers 1 by 1 again and test which one causes the crash

Good evening guys.

So in the last month I changed memory, cpu and finally I think my issues is coming from my Cache drives

If I do health tests on the drives they all seems to be good. I removed them and did tests in WIndows as well and all is well.

Can this be becuase of my 10Gb NIC card I have in the pci-e slot? Or Faulty motherbord ? Any other Ideas ?
