Periodically, once every 2-3 days, I lose access to the WebUI.   Dockers remain up, as do VMs and the shares are accessible.   Physical login from the console also works.   

 

Unfortunately due to that, I am unable to run diagnostics when it occurs.     The problem resolves itself on reboot.

 

Running the diagnostics command from cli just hangs the cli until i ctrl-c

 

I have attached diagnostics post reboot, although I suspect that will not be terribly useful

 

things I have tried already

 

1) Increasing the /var/log size before rebooting, so it is no longer 100% full.   This did not resolve this issue

2) Rebooting the webGUI

3) Saving off /var/log

 

Attached to this post is the diagnostics file from after reboot.  And the logs that are taking up all of /var/log prior to rebootscarif-vault-diagnostics-20230503-1142.zipsyslog.1

Try disabling Avahi since it's one of the things spamming the log, there's no GUI setting so you'll need to edit /boot/config/share.cfg and change

 

shareAvahiEnabled="no"

 

Then reboot.

did that, seems that far more of syslog.1 is filled with this though

55 mb vs 2 for the Avahi stuff

It is, but that can be caused by a previous issue, see how it goes after the change and a reboot.

Will give it a few more days, since it was an aperiodic problem, but that looks to have greatly reduced both types of errors in the syslog.

 

I saw that 6.12 RC5 has this change:

 

Restrict avahidaemon to primary interface.

 

I wonder if that would have fixed it?

Looks like its not yet resolved after the above.   That got rid of most the errors in the log, but I woke up this morning to no webui, no network.  

 

The gaming vm was still running, but only on local console, and I couldnt even get graphical console on the port

 

new diags attached.   Had to hard reboot

Enable the syslog server and post that after a crash, you should also update to latest rc.

enabled and writing to a survivable location.   Will update, and then post syslog when it happens again

logs starting to fill up again.  Thousands of entries of this.  Hasnt crashed yet

Try again after booting in safe mode.

Booted into safe mode @ May 10 07:31:43

 

Logs looks slightly different, but still a lot of NGINX spam.  Attached

syslog-192.168.1.10 (1).log

Now disable the docker service to see if it's any of the containers, but reboot first.

went away with docker off.  Turning each docker back on one by one to see who the offender is.

not resolved yet.   Took longer, but just went inaccessible again.   No telnet no ssh, no webUI shares and dockers are down.  But somehow the VMs are still up.

 

Will pull the off-system syslog later.  This is getting very frustrating

Same issue, syslog attached.   I have completely recreated all my docker containers, and removed and replaced the docker file and still have the issue.

 

This time I caught it live, and it filled up the log with

in less than 5 minutes.  

 

 

syslog-192.168.1.10.log

This is 100% tied to the cloudflared docker.     Logs do not fill, no signal 6 errors when its off.     

 

I would like to understand why at a more strategic level, Unraid bricks itself when the logs partitition is full, rather than logrotate or something kicking in.   Thats very poor behavior to brick the OS when logs fill up.  

Caught it process.  Diagnostics attached before the server locked up with a full log several minutes later.

 

At this point if this cant be resolved, I will have to switch off unraid.

If you already know which container is causing the problem you can post in the respective support thread/discord, assuming one exists:

 

Not sure which container you are using, but I'll mention that I've been testing the figro/unraid-cloudflared-tunnel container and haven't had any issues like this

I did, no response unfortunately since its not a universal problem with the container, but rather one with its interaciton with unraid.

The docker rollback in 6.12.2 fixed this issue thus far.  Been stable for 4 days now, couldnt stay up for more than 40 minutes before that.
