While attempting to listen for session requests from clients using TCP/IP, TCP/IP returns an error. The reason code is the return code from the TCP/IP listen API.
Server operation continues, but the server cannot accept additional sessions from clients using the TCP/IP protocol.
Ensure that TCP/IP is running properly. This may be done by issuing the TCP/IP netstat -s and ping commands to other nodes on your network. It may be possible to correct this condition by restarting the server.
