KB485599: When attempting to start Tomcat 9.x, users receive the error ' java.net.BindException: Address already in use: NET_Bind” in MicroStrategy Web.

Symptoms:
In the Catalina.out log, we see following error:

org.apache.catalina.core.StandardServer.await Failed to create server shutdown socket on address [localhost] and port [8005] (base port [8005] and offset [0])

java.net.BindException: Address already in use: NET_Bind

Cause:

1. Stop tomcat server, modify the shutdown port in server.xml (apache-tomcat\conf) file to a different one (e.g. 8006) and start the tomcat server.

1. Identify which process is using port 8005 and stop it.  We can get the PID e.g. from following command: Netstat –ano | findstr “port_no”, then, navigate to the task-manager, services and search for the this PID. For instructions on how to modify the default service port, refer to product documentation of a specific vendor. Alternatively, there is a possibility that restarting the machine will free the port up.
