Summary:                    Deadlocks with ~2k MGCP users
Description: 
I experience a freeze of Asterisk when I was in 1.2.35 due to 'Avoided
deadlocks'.

So I move to 1.4.29.1 release and the issue seems to be the same. One
difference : I don't have "Avoided deadlocks" into Warning level but only a
lot of "Avoiding" during the day and ONE (ie. On one channel) repeated
several times after Asterisk has freezed.

I can post some debug output but not backtrace yet because I must
recompile with DEBUG_THREADS = #-DDUMP_SCHEDULER #-DDEBUG_SCHEDULER
#-DDEBUG_THREADS #-DDETECT_DEADLOCKS

There are also a lot of Maximum Retries along the day.

Maybe it can be a trigger of the problem ?
