After having zero crashes/freezes these last few days, I'll mark this one as the solution and give some extra info: - Running Ryzen 1700X with 2133MHz RAM, no manual overclock - I deleted Pihole docker - I disabled the C-States completely and also turned off Precision Auto boost, 'cause I realisticly don't need the extra performance for my docker containers. Since then I've run without crashes, so I blame C-States. Still not quite sure what triggered it, it did start happening when I put the Pihole static IP on networt br0. No memtest yet. I'll re-add pihole and see if my system continues to be stable. If I don't report back, assume everything has worked.

So roughly since I first tried to install the pihole docker, my Unraid Server started locking up every night. I had to force-shotdown and restart every time, server would run normally until sometime in the night and be locked up again the next morning. Initially I thought it had something to do with Pihole, so I removed said docker. no change. The issue started in Unraid 6.11.something and is persistent after the update to current version. all plugins up-to-date. It took me a while to figure out persistent syslogs, now that I have them it seems there's some sort of infinite loop going on. I tried googling every single line, but imma be honest, I'm a Windows guy and don't understand most of what's going on here. So I'm coming to you guys for help. Can you point me in the right direction? Were do I even start with figuring this out further? Here's the part of the log that keeps repeating every ~30 seconds give or take.

you definitely saved my bacon after quite a bit of unsuccesful Google. Proper steps for anyone else wondering: 1. Login to docker from Unraid Terminal: 1a. Clock the Button for Unraid Terminal in the Unraid UI (top right, looks like the old console symbol) 1b. type "docker login" and press enter. you will be prompted for your name and password. (no encryption, make sure you trust the unraid install and check who can access it!) 2. create new container 2a. Go to the Docker tab and press "Add Container" 2b. in the "Repository:" field enter your repository in the format docker.io/[DockerUsername]/[DockerRepositoryname] 2c. Configure your container as needed 2d. Press "DONE"
