Constant 100% CPU usage by kworker process

Hi all,

I recently build a nas system and installed the latest version of Rockstor on it. Right away I noticed from the web UI that the processor usage never drops below 25% (Intel core i3-6100). After SSH'ing into the NAS and running top I see that kworker/0:1 is using roughly 100% of one thread of this CPU. As this system is pretty new I hoped that the process would actually idle out after some time, but after running the nas for a couple of weeks nothing had changed. Also, rebooting didn't resolve my problem.

The system I'm running is quite simple. The system boots from an USB 3.0 32GB stick and only one 4 TB drive is used for file storage. I do run a couple of rock-ons, namely plex, plexpy, nzbget, sonarr and couchpotato. However, shutting down the rock-on service doesn't resolve the problem. Does anyone knows what causes this or a way of running deeper diagnostics? Hopefully, you can help me resolve this problem.

Thanks in advance.
