While initializing TCP/IP communications, the server fails to connect to a master socket on which to listen for clients. The reason code is the return code from the TCP/IP bind API.
Server operation continues, but the server cannot accept sessions from clients using the TCP/IP protocol.
Ensure that no other application is using the port number specified in the server options file with the TCPPORT option by issuing the TCP/IP netstat command. If the server was brought down and client sessions were active, it may be necessary to terminate the client sessions on the client systems before the port can be freed.
