I just setup this machine and am completely new to unraid. Any help would be appreciated.

 

CPU: I7-7700k

Unraid 6.12.3

Background: Set the machine up 3 weeks ago and was running solid. The hardware I'd consider known good. It came from a pc I have been using for the past 6 years that was completely stable. Last Wednesday I started to have crashes when server has been sitting idle for hours, 1-2 per day. Today I started logging and I have attached the syslog and diagnostics. Today is the first time the server crashed while being used. I do not see anything that immediately sticks out to me as to what could be causing the crashes, but I am very new to this. I don't remember what day I upgraded to 6.12.3, but it was about the same time the crashes began. Before I roll back the earlier version I'm hoping that someone may see something that doesn't look right.

System just crashed again about an hour after coming back up from last crash. I have attached the logs from this one. 

 

Things I have done so far:

Verified all connectors are seated well on mobo, drives, etc

Docker is setup with IPVlan

VM's are turned off since I don't run any

Fix common problems shows writing logs to the flash as the only error

 

I'm going to restart the server in safe mode to see if the crashes persist.

syslog tower-diagnostics-20230830-1924.zip

Server crashed within minutes of restarting in safe mode. 

 

My mobo has 2 ethernet connections. Intel and killer. Last time I moved the server I changed from the Intel to killer when I plugged back in. I did not think it would make a difference but I have switched back to the Intel. 

 

I also went into the bios and changed the usb from legacy to uefi. I had read that legacy was more stable, but have changed it back incase that was an issue. 

 

There's nothing relevant logged, suggesting a hardware issue, run memtest, you can also try disabling c-states, though it's usually not needed with Intel it's been reported to help on some rare occasions.

I've started hardware diag, so far this is what I have tried, but I'm still crashing every few hours:

 

Removed HBA card so that only HDD connections are mobo SATA.

Reformatted my USB and recreated from backup.

Ran memtest for 12 hours with no errors. 

 

I reset my bios and will look to make sure c-states is disabled. 

 

Could the problem possibly be cache related? I run 2 1tb nvme drives for cache. Would removing 1 at a time to see if the crashes persist be a possible step?

Don't think that's very likely, but you can try.

Hi! Any resolution? I'm experiencing the same crashing after 3 minutes in. Ran flawless memtest (20 hours), SMART tests on all drives and CPU torture sessions.
CPU + RAM are not OC'd either.

Ended up being hardware. Server wouldn't start one morning. I pulled the mobo and there was a blown cap and burnt tracing. I can only guess the constant restarts were the board failing until it finally completely went. Moved my z690 and i7-12600k to the server tower and been running solid since.
