Unraid - locked up/hangs/frozen/unresponsive


Recommended Posts

Hi all

I've been chasing this issue for some time now; even through several versions of OS.  This is not something new on 6.8.3 (current os).  Unraid will randomly just lockup, freeze, become unresponsive.   I've tried using a COM/Serial port so I can monitor / access the system, and well that's locked up too.  No console/keyboard access nor http either.   Finally with the mirror option I was able to get a full syslog when this occurred.  Unfortunately, the log doesn't show any issue when the lockup occurred.   Full Diags are attached.

 

Lockup occurred some time after Aug 7 -- 1:10:56 am.    Reboot was at 8:33:34 this morning.  Nothing logged in-between.

 

Really hope someone has some insight.

That suggests more of a hardware problem, I would try running the server as a basic NAS, after booting in safe mode and without any dockers/VMs for a few days, if it still locks up like that it's almost certainly hardware, if not start enabling the other services one at a time.

Thanks @johnnie.black for getting back to me quickly.

 

Well that is unfortunate, but it probably makes the most sense.   Based on my current setup I really can't run with the system down (no VM/dockers) for extended weeks until this would occur again.   Most times it takes weeks and/or months for it to crop up, again.  Point being, it's pretty infrequent, which makes this really hard to troubleshoot and with no log errors or crash dumps, probably impossible to pin-point the piece of hardware.   Actually just about the time I forget the last time it locked up, it does it again.  

 

I think I might try just a weekly reboot... and see if that helps.   

 

Other than a memory or cpu stress test, if there are any other diag options let me know.  

Thanks again.
