Needing some assistance please. I've been having this issue for a few weeks. At 8:12 my Proxmox system finished backing up via NFS to my TrueNAS system. I have done this for a year now with no issue. The only change recently was 16GB to 32GB of RAM, but based on the error, I don't think that is the issue. The backup still completed fine, but it seems to kill python or a python process so I can no longer login. I have to ssh in and restart middlewared. The middlewared error below just continues repeating until I restart middlewared. I changed the backup time yesterday from 6am to 8am and sure enough that killed the login. Also, I have no jails. Just use this as a basic NAS for backing up.

Any thoughts on the issue?
