Thanks - no clues in the logs I am afraid - they only cover about 9 hours
The logs filled up quickly because of some issues that the transcoder encountered when transcoding for intro detection overnight for /share/CACHEDEV1_DATA/media/TV Shows/The Royle Family (1998)/Season 00/The Royle Family (1998) - S00E11 - [BBCi] [SD] [540p] - Joes Crackers.mp4 with over 275,000 error lines logged by the transcoder within a 5 minute period
i will raise this for the development team to look into transcoder error logging
