Since about August 2025, the server has had issues when mainly sabnzbd files are downloading, unpacking, unrar and repairing files and server can become temporarily frozen or unresponsive along with containers until files finish completely. This also causes problems with errors in Sonarr, Prowlarr and Radarr temporarily while files are in this process. These files download download, unpack, repair and unrar way slower than usual (since around August 2025), and this is even after replacing pool zfs drives, and to a fast 16 core processor. Additionally, during the exact same timeframe my docker has been glitchy with certain containers stating they update successfully (or fail) but still show updates are needed. What is going on? Why is this happening, as I did not change any settings whatsoever and the server was way faster before.

Attaching diagnostics zip file for consideration. Thank you for any help.

If possible, try using disk paths, or exclusive shares; using /mnt/user can sometimes cause that for some users.

Thanks JorgeB, I will try it and see if things change. Just don’t know why it suddenly changed.

So I did do change to exclusive shares and I still get the same problems. I did put docker and those shares on a fast M.2, but still have the issue.

If it still happens with exclusive shares, I would suspect a storage issue.
