[Freeswitch-users] Leg stuck in a conference

It looks like its in recvfrom.  What version of FS is this and what type of
call client etc is this?
Do you have proxy_media on or timers disabled?

It doesn't seem like this should be a likely scenario based on the
description and the code I'm looking at.  Have you tried to reproduce it
with master?
The break signal should cause the read to come up to the conference app
where it will detect that its done.
