Socket Question

I have a series of jobs that run in batch and spawn a bunch of socket
jobs.  Basically,  I used Scott Klement's sample socket programs and
modified them to do what I needed.  

Everything works really well, except that after the second or third (I
think) rendition of the socket listener spawning a new job the whole
thing just kind of hangs as if the sockets are all used up.  Now...using
Scott's design,  I spawn about 10 socket instances from the single
socket listener and from there as each spawned job finishes, I terminate
the program and the main socket listener spawns another socket, reusing
that now closed socket port.   And, as I say, it works fine for awhile,
but at some point it all just hangs. To "fix" this, I end the socket
jobs and restart them.  Then everything works fine again for awhile,
until, once again it hangs.

I'm wondering if the sockets ports are really being freed up like I
think they are or if something else is going on.

Suggestions?
