Thanks Anthony, I added the below line before esl_listen to ignore the sigchild, and it resolved the problem: signal(SIGCHLD, SIG_IGN); esl_listen(ip, port, mycallback); -MohammedShehzad On Tue, Jan 12, 2010 at 10:04 PM, Anthony Minessale < anthony.minessale@gmail.com> wrote:
It's forking process code. you need to ignore sigchld or create a sig handler for sigchld and use the wait syscall to reap the process.

Hello everybody,
I am creating a C program of ESL outbound for call processing. I am using testserver.c example, and till now it seems fine.
But i noticed that every call testserver process, a new process is being created which I can see in Linux system with below command: For example, when I make two calls and even after hangup, I saw three process like below: ps -A | grep testserver 9345 pts/2 00:00:00 testserver 9350 pts/2 00:00:00 testserver 9357 pts/2 00:00:00 testserver
This get increased for every call i make.
I did some workout and placed below two lines (close & exit) at the end of mycallback function, (as I found them on ivrd.c file):
esl_disconnect(&handle); close(client_sock); exit(0); } But after that the process becomes defunct/zombie
9440 pts/2 00:00:00 conflisten 9442 pts/2 00:00:00 conflisten <defunct> 9452 pts/2 00:00:00 conflisten <defunct>
Will anybody please suggest me how can I eliminate this process, which remains in memory even after call hangup?
Thanks for any response. MohammedShehzad
