Thanks Jim,
If I will use simply exit() also, I am getting the core dump. The problem is, there is a few second difference inbetween the processes were killed by 'exit' function and then restarted by another process. And by this time, if any input hit this server, it gives core dump. I used threading and then too, this did not work out. I want the input values to wait for some time or something same before the process get restarted again. Please let me know if you need anymore information.

EXIT(2) System Calls Manual EXIT(2)
NAME
exit, _exit - terminate a process
SYNOPSIS
void _exit(int status)
DESCRIPTION
_exit terminates a process with the following consequences:
All of the descriptors open in the calling process are closed. This may entail delays, for example, waiting for output to drain; a
process in this state may not be killed, as it is already dying.
If the parent process of the calling process is executing a wait or is interested in the SIGCHLD signal (Minix-vmd), then it is
notified of the calling process's termination and the low-order eight bits of status are made available to it; see wait(2).
The parent process ID of all of the calling process's existing child processes are also set to 1. This means that the initializa-
tion process (see intro(2)) inherits each of these processes as well.
Most C programs call the library routine exit(3), which performs cleanup actions in the standard I/O library before calling _exit.
RETURN VALUE
This call never returns.
SEE ALSO
fork(2), sigaction(2), wait(2), exit(3).
