Transcoding errors stopping stream

I’ve been getting some transcoder errors that are causing the stream to completely stop requiring a restart of the application. It seems to happen at random, on one occasion it has happened twice in a 24 hour period, and another it went about a week before having any issues.

I use Wowza to stream nearly 24/7, so its kind of a bad time when it conks out. Below are the errors I found the last time it happened.

Anyone encounter anything like this before?

This really looks like a capacity / overload problem. Is the CPU or GPU of that server running at max?

Nope, at least not according to the Wowza dashboard thing. Server is CPU only and stays right around 30%.
