Why is CPU 100% on one of the threads?

[katit]

System is pretty much idle right now. I checked - no Scurb running or anything like this. Yet - it shows 50% CPU (I assume one thread) taken by python? What is that? I thought it's one of plugins (I have PLEX and CrashPlan). Disabled and stopped PLEX - no change.

Start turning off services until it kills the process. Also please provide hardware and freenas version.

Python is usually Plex, or one of the download helpers (sickbeard, sonarr, couch potato, etc)

Added system details to my sig. I have only 2 plugins: Crashplan and Plex. I stopped both jails and turned off both plugins. No change. I stopped all services - no change.
Reboot helped. Any ideas on what that can be?

Turning off the plugin may not have actually stopped a job stuck in Plex. Did you stop the jail too?

 

[katit]

Yes, I did stop jails and then plugins.

I rebooted box, everything was 0%, in a morning - one CPU core 100% again. Stopping jails don't help. Uninstalled PLEX completely, rebotted and now it seems to stay normal. I wonder if it's a known issue..

 

[SweetAndLow]

Not a know issue unless plex is doing something. Maybe transcoding or indexing.

Things like this can also happen with operating system corruption---but with ZFS on boot, I think you'd know something was up..?
