after some hours of dialing , swap memory starts getting used and asterisk
gives core dump .

Asterisk is running with safe_asterisk.

vmstat ouput is as follows 

[root at localhost cron]# vmstat

2007 i686 i686 i386 GNU/Linux

Cannot do valgrind test as it put heavy load on the server and its a
production server .

RAM On the server is 2GB .

Only Asterisk application is running on that .

hi thanks for your prompt reply and appreciate you have taken a time out
and looked into our issue .

I ll explain you why we are using local channels and our dial plan as well
.

We are using a dialer application where we dial out the local channels and
when sip channels gets formed we transfer the call to the executives.

Local channel we are using because we send monitor and then change monitor
is required for recording the calls .

exten => _91.,1,AGI(call_log,10.0.0.5|10.0.0.190)
exten => _91.,2,GotoIf($["${CALLFILENAME}" != ""]?3:4)
exten =>
_91.,3,monitor(wav,/var/spool/asterisk/monitor/ORIG/${STRFTIME(${EPOCH},Asia/Calcutta,%Y%m%d)}/${CALLFILENAME})
exten => _91.,4,Dial(Zap/g1/${EXTEN:3},,o|)
exten => _91.,5,Hangup

Caller id is also required for transferring the call to the agents thats
why we are using ,,o as well .

At the starting local channel gets formed and after that SIP or ZAP
channel gets takes place and thats why we are using local channel .

We are using httpd and php for the web interface and other pages for
dialing and all .

------------------------------------

Today also in the morning we had one core dump but thats was not due to
hangup on local channel but due to 

Core was generated by `/usr/sbin/asterisk -vvvg -c'.
Program terminated with signal 11, Segmentation fault.

Attaching the core dump as well by the name of core.txt 

Will also upload the console output as well if again asterisk gets crashed
.

Thanks again for your response .
