| Hi all,
I have written a multithreaded program in C/UNIX using POSIX
threads (pthreads).
I am executing some UNIX commands using system() function.
If I am not passing any argument to the command...the daemon works
smoothly but when I pass arguments to it...after 3-4 (average)
executions the daemon crashes with error as follows:

Pls could you guide me on what could be reason for this? and how this

Waiting for your reply.
