Server Crashing - Need Help to troubleshoot

Featured Replies

Hello guys!

My server's been crashing for 4 or 5 days now. I still didn't figure what could be!
To make this post short. 
I run unRAID 6.11.5 for a long time and it was rock solid most of the time. I recently updated to 6.12.6, crashes started about this time. 
The thing is, I've installed 6.11.5 again and the system is still crashing. 

What I've done so far:
- Changed flashdrive to a new one
- Changed the usb port (from 3.0 to 2.0)

- Installed unRAID from scratch and didn't install any plugings or anything else, left everything pretty much in default (Disabled VM and Docker service) and just let my array run. I try a parity Sync and after few minutes the system crashes. Some crashes I need to manually power the machine off and back on. Lately I get no UI response from the GUI and after few minutes I get the login page again. The server reboots byifself. It seems to be a full reboot. 
- I also ran a memtest86+ for 20 hours and found 0 errors
- I physically unplugged and PCI USB card (just in case) 
- Didn't passthrough anything (didn't bind anything to VFIO). 

I basically installed unRAID 6.11.5, set the syslog client to send the logs to another device, disabled VM and Dockers services and then Started my array. I let the parity-sync run and after few min ~20 or so , the system rebooted by itself. 

 

Crash happened at Jan 27 14:24 

`Jan 27 14:25:41 Tower webGUI: Successful login user root from 192.168.1.207` 
That's the first line after the crash
I attached the diagnostics and syslog. 
Any help would be really appreciated, I really don't know what to do anymore to find the culprit of the crashes.

Thank you!!

Server rebooting by itself is almost always a hardware issue (or power), maybe the upgrade timing was just a coincidence, especially since downgrading didn't solve the issue, see if this has been taken care of but this usually makes the server hang/crash, not reboot on its own.
