Summary:                    [patch] Deadlock on &(&channels)->lock
Description: 
I've got 2 deadlocks in 3 days. It happens in a peak hours, with more then
a hundred calls in the system.

I've got 2 files 1 with "core show locks" - from the first deadlock (the
day before yesterday), second file - with output from gdb (intho thread,
thread apply all bt, thread apply all bt full) - from today's deadlock.

Now i have false-positives for rtp-timeout timers,

but rtp is works,

    -- Executing DIAL("SIP/1010-000017a4", "SIP/voipgw4/........")
  == Using SIP RTP CoS mark 5
  == Using SIP VRTP CoS mark 6
  == Using UDPTL CoS mark 5
    -- Called voipgw4/09689262415703
    -- SIP/voipgw4-000017a5 is making progress passing it to

    -- SIP/voipgw4-000017a5 is making progress passing it to
SIP/1010-000017a4
    -- SIP/voipgw4-000017a5 answered SIP/1010-000017a4
    -- Packet2Packet bridging SIP/1010-000017a4 and SIP/voipgw4-000017a5

Disconnecting call 'SIP/1010-000017a4' for lack of RTP activity in 61
seconds



I've checked "core show channel SIP/1010-000017a4" several times during a
call. It seems that Asterisk stops updating packet counters (Frames in,
Frames out) after a few seconds of call.
