card on ibm x3200 server and 90 active calls running on asterisk cli and
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

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 .

sorry for late reply , was trying for valgrind for so many days and have
tried running valgrind today .

Have upgraded asterisk to asterisk-1.4.19 version and also traffic on
asterisk has increased , due to which asterisk has given core dump many
times 5 times in a day .

The problems are like 

channels locking is taking place , show channels becomes unresponsive and
calls stops going .

On asterisk it shows congestion , unable to create zap channel type .

Attaching the core dump as well and valgrind.txt as well .

Waiting for reply as m in a very critical situation right now .
