While initializing TCP/IP communications for administrative sessions, the server has failed 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 administrative sessions from clients using the TCP/IP protocol. This also includes server to server sessions, storage agent to server sessions, and library client to server sesssions.
Ensure that no other application is using the port number specified in the server options file with the TCPADMINPORT or TCPPORT options. 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.
