The problem is simple and it occured in some previous versions of airtime. During the show (with content) the playout suddenly goes off. The "on-are" button alo goes in gray. The airtime stats are fine - all in green. I skimmed thorugh the logs and could not find antyhing suspicious.
Logs attached. I noticed the 'on air' button going off around 10:02 (09-10-2013). I hope this will be helpful,
Hey, did you do any modifications to your Airtime installation? I'm seeing a lot of requests for things that don't exist and I've never seen anything like this before.
