             Summary: 'Bad Magic Number' with bridge Application after ~150 bridges
                 Key: ASTERISK-22363

      Security Level: None
          Components: Bridges/bridge_simple
    Affects Versions: 11.3.0, 11.4.0, 11.5.0
         Environment: VMWare Virtual Machine  with 4GB RAM and 4 Vcpu, the environment is running over an hp server with 16 GB RAM and an Intel Xeon E5520 QuadCore Processor.

We are trying to use the Asterisk Bridge application but when we have more than 150 bridges, Asterisk shows the 'Bad Magic Number' error.
When the 'Bad Magic Number' error occurs the hardware performance is normal (CPU and RAM memory) without substantial increase.
we recompiled Asterisk following the Reference Count Debugging Document and we will attach the debug information.

Operating System : CentOS 6.4 Kernel 2.6.32-358.el6.i686 
Asterisk : Asterisk 11.5.0

this is the Dialplan for the case:

Global Variables
{noformat}
CONFBRIDGEVAL=4000
CONFBRIDGESMF=1
BRIDGELASTCHANNEL=string
{noformat}

Dial-plan
{noformat}
;;BRIDGE
exten => _X.,1,NoOp(${GLOBAL(CONFBRIDGESMF)})
exten => _X.,2,NoOp(${GLOBAL(BRIDGELASTCHANNEL)})
exten => _X.,n,GotoIf($[${GLOBAL(CONFBRIDGESMF)} = 0]?confbridge1:confbridge2)
exten => _X.,n(confbridge1),Set(GLOBAL(BRIDGELASTCHANNEL)=${CHANNEL})
exten => _X.,n,Set(GLOBAL(CONFBRIDGESMF)=1)
exten => _X.,n(play),Playback(tt-monkeys)
exten => _X.,n,Wait(10)
exten => _X.,n,Goto(play)
exten => _X.,n(confbridge2),Set(GLOBAL(CONFBRIDGESMF)=0)
exten => _X.,n,Bridge(${GLOBAL(BRIDGELASTCHANNEL)})
exten => _X.,n,Hangup
{noformat}

Steps required to reproduce the issue :
using the dialplan above, create more than 150 bridges.

Thanks in advance!
