Recording stops after few minutes, trying to understand why from the logs

I’m trying to record “Sesame Street” (30 minutes long episodes), and of the 7 episodes I’ve recorded so far, all end up stopping early, somewhere between 2-20 minutes.

For example I had “Big Bird’s Song” scheduled today from 11:00 to 11:30, but I see the following message at 11:08:

Nov 21, 2017 11:08:43.700 [12052] DEBUG - Killing job

I don’t see any message that indicates an error, so I’m trying to understand why “Asked to stop recording” is occuring at this time. Anyone can give me any pointers for what else to look at?

I attached the Media Server log, please let me know if there’s another log with relevant information.

Server version 1.9.6.4429

Thanks!
