Workflow get corrupted because of constant (failing) reingest of mediapacakge from the capture agent

Steps to reproduce:
1. Somehow the capture agent fails to ingest the recorded mediapackage (Error 500) but the core successfully received the mediapackage and processes it.
2. The capture agent continues to ingest the mediapackage and always fails again. But the mediapackages are all received and processed. In the speed they get ingested to the core the all get to the prepare-av operation and I'm getting more and more jobs for the ffmpeg on only one of the worker doing excactly the same.
3. The workflow for the job gets longer and longer with each ingest because each ingest adds the new operation to the same workflow http://pastebin.com/1B6YdSkF
