HW Transcoder Crash

Server Version#: 1.15.4.993
Player Version#: Roku 2

Every now and again when a movie transcode session starts my server hardware transcoder crashes and reverts to software thus hogging the CPU. If I kill the Plex Server and re-start it everything resumes to normal. I have a small snippet of the log below. I have a copy of the full verbose log if that is required also.

This is still an issue as of 1.16.0.1226.

Once again, killing and restarting the plex server resolves the issue.
