player stops after append new live stream

Hello ! Sometimes, after append m3u8 by chunks from new session, player stops after few seconds. In vod mode this part of m3u8 playlist works fine. Sessions separated by #EXT-X-DISCONTINUITY tag. Console log finished by multiple lines with next message:
DEBUG:position/duration/buffer/backBuffer/audio/video/NetStream bufferLength/audioExpected/videoExpected:0.00/53.67/31.38/-0.05/26.31/26.07/5.31/true/true
In safary browser and iphone live playlist works without any problems.

No file, test, or entry point is named. Reproduce the failure by appending chunked m3u8 content from a new session in live mode, especially across #EXT-X-DISCONTINUITY, and compare it with VOD playback and Safari/iPhone live playback. Done means the player continues playing the appended live stream without the reported buffer state and stop.
