[6.11.2] Complete Unraid Server Freeze-up

I have the same problem.

 

 

Enable the syslog server and post that after a crash.

Nothing relevant logged, that usually suggests a hardware issue, I would start by downgrading back to the previous known good release to confirm it's not happening there now.

Had reverted back to 6.10.3 when I started this post, so about 2-1/2 days in and no issues on the old version.  I'll check back in a few days.

Now 6 days in with version 6.10.3.   Appears to be an issue with the new version of Unraid and not a hardware problem (unless it is compatibility).

It does suggest some compatibility issue with the newer kernel but with nothing logged it's difficult to say for sure, look for a BIOS update and/or try 6.11.3, or the next release.

Ok, so found a BIOS update and made the update.  Restarted 1st with 6.10.3, ran for a day or two no issues, so tried the new 6.11.3.    Same problem has happened again after about 2 days.....complete frozen server, can't talk to the server and my router shows the computer not even there.......    Forced to hard reboot and again parity check is running of course for the next couple of days.   This is really a pain.  No way to troubleshoot since no errors in the log that appear to amount to anything.  I would like to just stay with 6.10.3 for now.... but what are the security risks?  Are there separate security patches that can be installed in the meantime to 6.10.3?  I see the Unraid website shows 6.11.4 and my server is now saying 6.11.5 is available.      This can't be good for all of my hard drives......  Lost on how to proceed.....

Changed Priority to Urgent

May be try disable SMT then VT-x / Vt-d

Let the parity check finished, rebooted, and disabled SMT.   Less than a day later, complete server crash again..... trying to disable VT-x / VT-d now..... not looking promising.

So disabled everything noted above. Less than 6 hours after the parity check completed the server is again frozen and unreachable. It does seem odd that the server seems to keep churning along while the parity check is in progress (which takes about 1-1/2 days) and than it fails several hours later while the system is idle.  Something going to sleep??  The last several times it has crashed I’ve not seen anything in the system log of a recent error etc.

Almost same symptom have found in 1st gen Ryzen due to CPU enter idle ( low power state ), but this can fix by disable C6 power management in BIOS. You may try similar setting in BIOS.

 

I have Intel 3rd gen, may be I can make some test on it.

 

Edit : No problem in idle for 9hr uptime ( 6.11.5 , 3570K no VT-d )

Running clean so far on 6.11.5 after I disabled the C6 power state.   Been a little over a day now.... Crossing fingers.

Good sign 👍

Over 3 days now.... so looks like that fixed it!   Thanks for the help!  Seems weird that the prior version 6.10.3 of Unraid didn't have a problem with that setting, but working anyways!  Marking as resolved.
