TNS-01106: Listener using listener name string has already been started Cause: Another listener is already listening on one of the ADDRESSes specified. Action: Shutdown the previous listener specified by the listener name before starting this one.
Have you tried the above step first? Note that ADDRESSes are not limited to TCP protocol. Perhaps you have a conflicting IPC key? What are the results of the "netstat --listening" command run as root?
Break the problem down through process of elimination. Double-check your ORACLE_HOME settings when starting each listener. Eliminate all but one ADDRESS for each listener, and then add them back in one at a time.
But, as Mladen stated, there is rarely a reason to run more than one listener per machine. Why do you need to do this?
