Description of Issue
After upgrading to 880, RoonServer on the Synology will restart itself every few minutes whether playing music or not (although I can force it to happen by playing any track, with the client losing connection to the server around every 2mins).
Logs show the following error over and over again:
12/17 10:06:51 Critical: scx: in OnExit: System.NullReferenceException: Object reference not set to an instance of an object.
