you can see here a 22165 allocations for 240 bytes, that was not released
(other are not so significant, but can be the same trouble).
and their count is constantly growing.

what else can i provide to find out a place of leak?

ps: valgrind is not an options, due to very huge slowdown. i've tried it.
:(

  Fix a memory leak associated with queues.
  
  For every attempt that app_queue made to place an outbound call to a
queue member,
  we would allocate a queue_end_bridge structure. When the bridge for the
call had
  completed, we would free the structure. Unfortunately not all call
attempts actually
  end up bridged to a member, so we need to be more selective of when to
allocate
  the structure. With this change, the allocation occurs in an area where
we can
  guarantee that the call will be bridged.
