You need to set the Listen value to either 1 or 0 depending on your OS. Note that this is not always supported. What will happen, is that one request will be queued until one process gets the chance to take it. This still has the inconvenient that you might have one connection stuck in listen state until one of the processes becomes ready again.

I guess a better approach would be to have a single "dispatch" process that takes care of the children and the socket. The client would connect to this main socket and receive the address and port of a vacant server (or a new server would be fork()ed to handle this request, up to a maximum concurrent number of children/operations).

This would be much more portable and reliable.

Perhaps a bit more information about your problem and scenario could help us better help you :)

Regards.
