Potentially a silly question, but if you don't ask you'll never learn... I recently switched my SSD Cache drive to use zfs instead of btfrs and since then I've noticed that my CPU usage will top out at 100% for long periods of time, seemingly at random. I'm running a fairly old but otherwise reliable N54L so it's fairly noticeable and am trying to troubleshoot a separate php issue since upgrading from 6.11. I've used the CLI command htop which shows it's usually a docker run command that's the culprit. Looking at my docker settings I can see the data-root is still set up to use to btrfs vDisk, should I change this either xfs or directory now the cache drive it's on is no longer btrfs? I haven't seen this accounted for in any of the conversion tutorials or docs, so am not sure if there's a best practice.

Just to chime in with my experience, I've been having the same errors since upgrading from 6.11 but have never had Dynamix Cache Dir installed. I've managed to narrow my issues down to mostly occurring after or during Appdata Backups has run. I'm not saying it's specifically that plugin that's the cause of the issue, just that I can successfully cause enough php errors to completely tank Unraid even with no WebGUI windows open by triggering a manual backup operation.

Thanks! That didn't quite end up doing the trick for me - ended up having to replace the db with a copy from a recent backup.

Yep, noticed the same thing this morning.
