December 5, 20241 yr I have been running an Unraid instance for years without much issue. It's a 12600k with 64GB of RAM, 8 HDDs (array), and 2 SDDs (cache). However all of a sudden my Unraid instance is running super slow. I could use some tips/advice on diagnosing it. My appdata and system shares are set to run on cache (always have). None of my disks are full, cache is around 50%, most of the array is at about 65%. A couple things I have noticed.: - The cpu is working awfully hard despite me having stopped most docker containers and all vms. I can see on the dashboard its always sitting around 65% and yet in the console I can run htop and it doesn't reflect this same level of usage. Not sure why, does anyone know? - Just trying to stop a small docker container with no activity I see the CPU spike to 100% and it takes 5 + minutes for it to stop. - As a last ditch effort I have fully updated to the 6.12.14 and the issue persists. So no change from being on 6.12.13 for a while. I am pretty certain the issue is with docker. Just trying to open Settings > Docker takes 5+ minutes while other parts of the UI are snappy.

December 6, 20241 yr Author Thanks for the reply JorgeB. I have been busy troubleshooting so I wanted to post some updates here. New information: I noticed my USB stick seemed to be failing so I created a new one from backup and applied it. After booting up I noticed that performance had improved. I then began to slowly turn on my various docker containers. After turning on a few I suddenly noticed my logs were filling with docker networking change notices over and over (occuring every few seconds). This made me very suspicious of a bad docker so I started turning them back off and I am now going through the process of figuring out which one is causing the issue. I am still a bit suspicious that my new USB stick isn't the best so I have ordered some new ones and I have opened a ticket with Unraid support to request a second unraid usb migration since there is only one auto one per year.

This could be a container constantly restarting, check their uptimes, it may help to identify it.
