November 6, 2025Nov 6 Hello Everyone,I've a recurrent problem since using Unraid (I started like 5years ago).As soon as some of the CPUs hits 100% (mostly due to either unzipping or SMB transfer), the whole server freezes:I don't know if I've missed some setting.Is also strange that only a couple of cores are so busy when extracting a .rar/.zip for example (which normally happens trough a Docker container / JDownloader)Any advice is appreciated.

November 21, 2025Nov 21 Community Expert I've seen over the years some users with similar issues. It's unclear why only some are affected, test writing to a disk share (or exclusive share) to see if it helps, it usually does, if you can make that work for your use case.
