        Can you report this upstream? Seems like maybe some minio issue. Is this all the time or only during some backup or some operation?

        I don't see the high CPU use in our minio instances atleast. Is anyone else see high CPU usage?

          @girish IDK that it is an upstream issue.

          I restarted, stopped, and started it several times, each time it goes into the above state.

          This instance has been running idle for quite some time, so it could be a configuration issue with a recent update or something similar.

          New install doesn't appear to do that.

            @robi It seems like some upstream issue. The config.json is somehow missing the scanner key, not sure why. But running mc admin config reset myminio scanner using the CLI tool seems to fixup your instance.
