If an SAP Sybase IQ server is running and you attempt to start another SAP 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 does not start, run the stop_iq command (UNIX) to display the names and port numbers of SAP 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), SAP Sybase IQ generates an available port number.
Trying to start TCPIP link ... Unable to start on default port; starting on port 49152 instead TCPIP link started successfully Now accepting requests ... Server started successfully
