Summary:                    Asterisk blocked when 2 or more users leave a meetme
when announce user is on
Description: 
If option I is used with meetme and 2 or more participants leave a
conference simultaneously, Asterisk stops working properly.  As the number
of simultaneous users leaving increases, the affect on Asterisk is
increased.

When the users hangup, zap channels stop accepting calls until the "user
has left the conference" message has played.  When several users leave
simultaneously the dialplan stops executing.
console commands such as meetme and core show channels will stop working. 
Sometimes the response is delayed by a few seconds and sometimes nothing is
returned at all.

When a larger number of users disconnect at the same time, Asterisk
becomes completely unusable without a restart

---------------------------------------------------------------------- 
When I hear that there's slowdown and that certain commands stop working,
my first thought is that there may be a deadlock.

If you can, please recompile Asterisk with DEBUG_THREADS enabled in
menuselect. Then when this happens again, get the output from the CLI
command "core show locks" and attach it here to this issue.

Thanks!
