System randomly unresponsive, only physical reboot helps

[A1DAN]

Hey all,

hope someone has some idea. Since I have moved to unraid I have the situation, that the system becomes unresponsive at random. Can't access the Dashboard or Docker anymore. Noticed, that the dockers are still reachable. Also the system gets really hot and fans are spinning like crazy. Only help is to physically reboot the system.

 

System is a

• Intel NUC10i5FNB
• i5-10210U CPU
• 16 GB DDR4

 

My System Diagnostics are attached. Unfortunately, as the only thing helping being the reboot, and in the meantime I am not being able to reach the Dashbaord, I could not capture SysDiags covering the time the problem occurred.

Note: I mirror for a while now the Syslogs to the USB. Cannot see anything unusual in there. The current ones are quite fresh, after a reboot I did, to do a memtest. Also nothing unusual. I did check the USB Stick with Disk Utility in Mac. Also seems not the problem. 

My current avenue is twofold: 

• I try to find out, if it is one of the docker containers. Unfortunately I cannot reach Docker when then System is unresponsive, so the logs are gone after reboot. I wanted to setup Netdata for that. Would you recommend? Or is there something better?
• I deactivated AdGuard Home, as it is the only container being on his own Network Type br0 and I see it wants to be in 192.168.178.0/24 and in 172.17.0.0/16 maybe this messes somehow?

 

Would really appreciate good ideas, as I went through the forums quite extensively over the last months and seem not to have found the issue with my particular case.

Enable the syslog server and post that after a crash.

[A1DAN]

Ahh, I think I always did it wrong. Did it now, let's see, when we see the next crash.

Now having the situation of the crash, with the current Diagnostics Docathena-diagnostics-20240531-0639.zip

Do you see something? I find the nginx weird

 

What I also do not understand: I set the syslog server to be on the appdata share, which is cache, around 13.50. After then, there are no logs aanymore. But also in the /mnt/user/appdata I do not see a logs file or folder. Did I set it up wrong again?

Possibly, post a screenshot of all the syslog server settings

[A1DAN]

Sure. Thanks for being so patient

That has only configured the syslog server in "Listen" mode.    As mentioned in the syslog server link you need to fill in either the Mirror to flash option or put your Unraid server's address into the Remote syslog server field to actually start getting something recorded.

Ok, wow, that was not transparent to me. Didn’t get, that that is a precondition. Did now. Thanks a lot. Then I wait for the next crash now.

I finally have a Systemlog for the situation of the crashes. I will start researching, but maybe you have also ideas?

Ok, judging from those: https://forums.unraid.net/topic/150670-solved-squashfs-errors-failed-to-read-block-and-locked-up-mntcache/ & https://forums.unraid.net/topic/129218-solved-kernel-squashfs-error/

I guess it is the flash, which I got new when setting up. So maybe it was faulty all along.

Got new flashdrives, will do Changing the flash device | Unraid Docs

Yes, the flash drive is having issues.

I can say, after switching to a new USB Flash drive, that the issue is no longer happening. Switching to local logging was important. Thanks guys
