WebGUI unresponsive - Getting 500 Internal Server Error

[jbquintal]

Hi Everyone, for some reason I can't seem to access the webGUI.  I took a look at a few threads with the same issue and tried some of the solutions, but nothing worked or isn't applicable.  I'm currently doing a pre-clear of two drives and a parity check.  I'm able to access the machine via SSH and things seem to be working... All docker apps seem to be working just fine and are reachable via their respective webGUIs.   

 

 

 

That being said, I've attached my diagnostics file to see if anyone can help figure out what's wrong. I'll keep it up until the parity check finishes and I'll do a reboot to see if that resolves the issue.  By the way, is "powerdown -r" the right way to gracefully shutdown?

Apologies for not outlining what I've tried.  In any case, here's what I've looked at so far.

There has been some back and forth between Unassigned Devices and Preclear development recently so maybe something to do with the preclears?

Thanks.  I did notice the Unassigned Devices error keep cropping up.  I did a quick search before and it just says that it's caused by having multiple browsers open.  In any case, i'll just finish the parity check and reboot the server and observe if it'll happen again.

"powerdown -r" is the proper way to do it, right?

I hadn't needed to do that recently so I checked the code:

root@unSERVER:~# which powerdown
/usr/local/sbin/powerdown
root@unSERVER:~# cat /usr/local/sbin/powerdown
#!/bin/bash
logger "/usr/local/sbin/powerdown has been deprecated"
if [[ "$1" == "-r" ]]; then
  /sbin/reboot
else
  /sbin/init 0
fi
root@unSERVER:~#

Looks like that would log that it was deprecated and then go ahead and do

reboot

instead

I rebooted the server as soon as my parity check finished.  I'm able to access the WebGUI now.  I'll update this post if it acts up again.

I'm not sure why this was so difficult to find or answer but here is how to correct the error without restating the machine.

From the console, log in to the terminal using the Root account. Once logged in type the following command:

/etc/rc.d/rc.php-fpm restart

Done. You can now log back in via WebUI.

I dealt with this exact issue today and your response fixed things perfectly. Thank you.

I have the same error but this did not fix the issue.

I am running into this issue regularly... I was fiddling with CPU isolation and pinning recently but can't think of anything else I changed that could be responsisble... anyone figure anything permanent out?

 

update: remove GPUstatistics plugin as that was identified as a potential culprit by others, waiting to see if the issue is resolved...
