Directory Services Service keeps shutting off

Hello,

I am running Freenas V. 9.2.1.3 with directory services enabled so that my Plex Server can read the data and stream videos off of it.

For some unknown reason for the past few days, the directory services service shuts off, and I can't seem to pinpoint why. I'm by no means a FreeNas expert, so if anyone has any ideas please share.

Thank you
