This is the second time this has happened. The first time, I thought it was corrupted memory causing the problem but I replaced those modules. I tested the memory again after with no issues. Unraid says my cache is full but at the same time reporting 406 GB free out of 500. Cache is a 2 disk raid pool (500 GB each). Dockers will not load. If someone could please look at my diagnostics and help find this new cause. Thank you.

Just a quick look at the logs and your drive config shows some sort of BTRFS corruption.  Without digging in further, I cannot say for sure but there is a possibility that the memory problems lead to corrupt filesystem or you have a bad drive/controller.  I say this because the high number of errors in the SMART stats and the system log entries like this one:

I would start by using a known good drive for cache or testing it on the array to rule the drive out.

Cache filesystem is corrupt, yoy should back up and re-format, but if this keeps happening it could point to a hardware problem.

This is the docker image, Unraid can't write to it, just a consequence of the pool filesystem going read-only.
