Did your check Gary Duzan's comment ?
"   If the program is forking off processes, perhaps the child processes aren't closing the socket file descriptor. Using fcntl() to set FD_CLOEXEC on the descriptor in the parent may help."

Another thing is you need to make sure that your processes are actually killed (not hung or become zombie).

They are closed if application is actually killed.
