The problem is an integer overflow on "after_init_list_dur" variable.
It happens about 30-40 minutes after starts hls streaming but strongly depends
on other options like "start_number" or "hls_list_size".
VOD or EVENT hls playlist types are not affected by this bug.
(P.S. I hope this text will be the body and not the subject :) )
