this happen when internet connection breaks or gets much weak.
crash can be reproduced using XSplit Broadcaster.
Steps:

Start FTL stream from XSplit Broadcaster to Mixer.
Limit XSplit Broadcaster upload speed to 1kbps using NetBalancer software.
Stop FTL stream.

I debugged this problem and found that ftl->status_q.mutex
was deleted by ftl_ingest_disconnect function, while some threads like ping_thread
are still alive and continue calling FTL_LOG with deleted ftl->status_q.mutex.
