Description
Tomcat by default listens on TCP port 8005 to accept shutdown requests. By connecting to this port and sending the SHUTDOWN command, all applications within Tomcat are halted. The shutdown port is not exposed to the network as it is bound to the loopback interface. Setting the port to "-1" in $CATALINA_BASE/conf/server.xml instructs Tomcat to not listen for the shutdown command.
