I went to restart my server after some GUI funkiness (elements not responding, dialogs closing immediately after activating etc) but unfortunately its failed to come back up cleanly.

The local and remote GUI's return a 500 nginx error and when I ssh into the server it shows docker and nfsd fail to start but nothing else obvious.

I've tried rebooting into safe mode as well as removing all peripherals and using a new flash drive all to no avail.

The only significant changes in the days prior to this was upgrading from starter to unleashed along with expanding the array, which had been stable for a day or so until just before I rebooted after the GUI issues.

I have been able to boot to a fresh copy of unraid so it appears to not be a hardware issue, and copying the config folder from my previously working (now broken) setup onto a working freshly flashed drive results in the same errors occurring so I'm assuming its a config issue.

I've hopefully attached the most recent diagnostics (taken after the first reboot failure)

Any ideas are very very welcome!

Nothing obvious that I can see, but if it works with a stock install it suggests a config issue, you can try redoing the flash drive, backup the current one first and then recreate it using the USB tool and just restore the bare minimum, like the key, super.dat and the pools folder for the assignments, also copy the docker user templates folder (\config\plugins\dockerMan\templates-user), if all works you can then reconfigure the server or try restoring a few config files at a time from the backup to see if you can find the culprit.

Any luck figuring this out? I updated from 7.0.1 to 7.1.4 and i can ssh fine, but i have no UI access.

Edit: I figured this out after doing some digging. I had been experiencing some issues with nchan logs and some memory leak with nginx. I had added the following line to my /boot/config/go file:

sed -z 's|nchan publishers\n\t#|nchan publishers\n\t#\n\tnchan_shared_memory_size 2M;|' -i /etc/rc.d/rc.nginx and my nginx logs were complaining about duplicate directives for that. They musta fixed it upstream so when i commented that out and restarted, everything was back to normal. Hopefully this helps someone.
