Thanks for the reply, and I've just confirmed it has stopped with the service emby-server onestatus.
I then restarted it with service emby-server onestart, and then the onestatus cmd returned :
emby_server is running as pid 81093.
Emby is notlocated in the/var/db directory, andf don't know where it would be.
When I went to the Jails tab and the the Storage tab, I saw that the Plexmediaserver plugin was mounted but the emby plugin was not mounted, so it is mounted now. I would like think that that was the cuse of the problem, but wonder if emby server does stop, does it automatically get unmounted?
