Summary:                    Asterisk Hangs/ CPU Usages goes up to 500%
Description: 
Asterisk 1.8.2 goes down, i am unable to stop from CLI. i have to kill PID.
I enabled don't optimize and dead locks for tarce and now what i see is
asterisk is consuming 500% of CPU. Once CPU usage goes above 300%, asterisk
start losing peers, peer lags ( Peer 'peername' is now Lagged) and after
few mins peers come reachable (Peer 'peername' is now Reachable). I have
attached the core show locks and back trace when CPU usage was very
high(300% or more). Total 850 peers, 80% are TLS. I tired 1.8.2 and
1.8.2.3, getting same issues with both. 
Linux Dist: Ubuntu 2.6.32-21-server.
Linux VOIS8P 2.6.32-21-server https://issues.asterisk.org/view.php?id=32-Ubuntu

I have attached the core dead locks and backtrace. I same exactly same
server running asterisk 1.4.37 with 1500 peers. 
 
Thanks in advance.
