I keep having issues where Sonarr will suddenly stop working. I just looked through the logs and found the following:
EPIC FAIL: Object reference not set to an instance of an object: Object reference not set to an instance of an object
System.NullReferenceException: Object reference not set to an instance of an object
at (wrapper remoting-invoke-with-check) System.Threading.EventWaitHandle:Reset ()

I’m running on Ubuntu 14.04
