If a Sybase IQ server is running and you attempt to start another Sybase IQ server on the same machine using the same port number, messages appear in the server log file (*.srvlog).
Trying to start TCPIP link ... TCPIP communication link not started Unable to initialize requested communication links ... DBSPAWN ERROR: -85 Communication error Server failed to start
If you see these messages in the server log file and the server will not start, run the stop_iq command (UNIX) to display the names and port numbers of Sybase IQ servers already running on the machine. Then try to start your server, specifying either a port number that is not in use or no port number. When you start a server and do not provide a port number (and the default port number is already in use), Sybase IQ generates an available port number.
