Bad Magic Number Error Using Bridge Application

Hi everyone!
I´m trying to improve my PBX conference performance, I researched on improvements in Asterisk 11 and I found ‘ConfBridge’ and ‘Bridge’ Applications, but when I´m using ‘Bridge’ and want to have more than 160 conference the application shows the ‘Bad magic Number’ Error, I think that the conference number isn´t the problem taking into account the characteristics of my server:

-4 Cpu

-Centos 6.4
-Asterisk 11.3

Additional Information
I have another Asterisk Server to launch calls against my test Server, this is my Dial-Plan:


;;exten => _X.,1,NoOp(${GLOBAL(CONFBRIDGESMF)})
;;exten => _X.,n,GotoIf($[${GLOBAL(CONFBRIDGESMF)} = 0]?confbridge1:confbridge2)
;;exten => _X.,n(confbridge1),Set(GLOBAL(BRIDGELASTCHANNEL)=${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

Do you Have any idea?
Thanks in advance!

Ideally you should breakpoint the code on the generation of that message and obtain a backtrace, then submit a bug report. The code must be compiled with optmisation disabled.

Subject to seeing the actual error message, I think this will be a memory corruption problem, so if it is possible to reproduce it in a lab environment, without high traffic volumes, you should run under valgrind. See the bug reporting guidelines.
