I am have a licensed wowza 4.1.2 with transcoder groups for \_mobile and \_all .

I have RTMP livestreams named with hashes coming in, e.g f44f03e72224749eed3682ee4e90be5c

Usually the transcoder groups works fine, but intermittently I get empty “playlist.m3u8” for the groups, and the wowza management gui shows ungrouped streams.

When this failure happens it works perfectly fine to view the ungrouped streams (e.g \_360 , \_240 e.t.c).

I have noticed that this happens quite frequently when the stream-names are re-used, I believe it also might happen after the stream has been running for a long time.

Any ideas how to move on to solve this problem ?
