Keywords: ports freezing
I found that when I set SLISTEN to a particular port#, and the connect script uses SCONNECT to the same port# it also changes each time (???) usually by increments of +2 (ie start at 1490, and next time it shows port 1492, 94, 96 etc). It also may not even use the port I select, instead starting somewhere else and incrementing from there.
Is that why it freezes, eventually running out of ports? Or is it taking the next available port?
Is there a way to specify and use just one port?
The port you connect to - or listen on - is like the "receptionist" port. When you connect to the sListen port, the receptionist does the real connect on a different set of ports and goes back looking for more connects.
If you don't do the SClose, then you can run out of ports. It should be able to re-use closed ports.
Once you get a connection, leave the connection open for pretty much forever.
