Controller resets sporadically, when it comes back online there is no database found in the controller (all points have been deleted) and it needs to be reloaded. After reloading, the Controller responds very slowly and time SystemVariables such as Date, Minute, Hour, are not updating.

The problem ended up being traced down to some XDriver points that were configured with an annex point that was also configured as an XDriver point. They were fighting each other.
Removed the XDriver point configured as an annex point in another XDriver point and the Controller started to respond normally.
