Unraid 7.2.0 - Server freeze when CPUs hits 100%

Featured Replies

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.

Does it recover after the transfer ends?

Yes.

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.
