So this has recently started happening in the past week or so. The webui appears to be failing to report everything, or even act on simple tasks. For starters, here's some screenshots I took of the issue.

 

 

 

I ran top to see what processes were running and see if there was anything obnoxious happening.

 

 

When the UI is like that, everthing appears to be functional. Deluge is still working, Plex is still serving content, etc. I have tried to reboot via the UI but that doesn't do anything; I need to reboot by command via terminal.

 

That all said, the first time I encountered this was after I had uploaded ~200gb to my rclone mount. I had setup the rclone w/ encryption a week or so ago, and had tested some small uploads, and confirmed it was working, and had no issues. I then queued up ~200gb to sync with that folder, and shortly after I noticed the UI looked like that. Since then this issue has cropped up 3 more times, although I haven't done any further uploads. 

 

As you can see I'm still on v6.6.7, I haven't updated to v6.7 as it's been a mixture of me being lazy, and I had read some reports of users Sonarr db's having issues.

 

I have a total of 4 drives, 1x10tb parity drive, a 500gb SSD for cache, and using a 32gb Sandisk USD drive for the boot device.

 

Any suggestions, let me know. 

 

Thanks

It looks like the system is waiting for some I/O to complete.  What happens if you stop Plex at the point this is going on?  That, and diagnostics may show something.

I'll have to wait for it to fail again to try stopping Plex. I did just now go through and update some outdated plugins... also rebooted as rclone-beta wasn't  updated; that's now been updated. I noticed the issue most recently around 4am EST, but here's the diagnostics log I just grabbed after the reboot.
