ERROR:updateFragment:seqnum 37952118 not found!

Nobody has claimed this yet.

Hi, Guillaume.

Live playback stops after a some time with error:

> DEBUG:Loaded 37952118 of [37952124,37952127],level 0 m/M PTS:617713/619633
> ERROR:updateFragment:seqnum 37952118 not found

Why flashls needed this very olders segment #37952118 (-10 sec ago from current MEDIA.SEQ)?

FF44 - often it happens, Chrome48 - rarely.

Start by tracing the updateFragment and loadnextfragment paths against the logged live playlist and its EXT-X-MEDIA-SEQUENCE values. Use the provided playback logs and master.m3u8 request to reproduce the failure, then determine the conditions that lead to the seqnum-not-found and Error #2032 messages.
