Unraid server becomes unresponsive

[Zotarios]

I've been encountering an issue with my Unraid server that occurs approximately every other month.

The problem manifests as follows: While I can still establish a connection via Wireguard, the WebGUI becomes unreachable, SSH connections time out, and all my Docker containers become inaccessible. The only recourse I have is to manually press the shutdown button on the server's case, wait for it to power down, and then restart it.

I've searched through the syslog for any relevant information but haven't found anything of significance.

I would greatly appreciate any tips that could help resolve this recurring issue.

Furthermore, I am attaching the system diagnostics, but I think it only has info since the last boot?

 

This is the syslog:

Add syslog info

Enable the syslog server and post that after a crash.

Tonight at 1AM approx became unresponsive again and this morning it was up and running, it didn't reboot or nothing.

I could connect to the WireGuard tunnel but dockers, SSH nor webgui were working

I see a lot of:

Feb 10 23:54:27 Zotarios flash_backup: adding task: /usr/local/emhttp/plugins/dynamix.my.servers/scripts/UpdateFlashBackup update

On my syslog log, but I don't know if this is the cause of the crash…

Try booting in safe mode and/or closing any browser windows open to the GUI, only open when you need to use it then close again.

[Zotarios]

I could boot into safe mode, but then I needed to boot in normal mode for server normal operation.

There is still this command in the syslog which is issued every minute all day:

"flash_backup: adding task: /usr/local..."

I don't think this is at fault for the server unresponsiveness, yet it's kinda annoying. I deactivated the flash backup with myunraid plugin as it was it that was filling my syslog.

Furthermore, I'm not logging into the GUI with a browser, just checking the logs via SAMBA.

add info

Just a thought - are you up to date on the Connect (MyServers) plugin?    That looks like a message that would be generated by that plugin.
