java.net.BindException: Address already in use:8080

After several times to reload the deployed application in tomcat on Mac OSX. I found the tomcat fail to start with this exception messages.

It's obviously that there has another process occupied the port 8080 or 8009. I uses the command, "lsof -i | grep LISTEN" to check the PID of the process that using the port.

imachome:/usr/local/apache-tomcat-5.5.20/logs chanapps$ lsof -i | grep LISTEN
java 298 chanapps 11u IPv6 0x2e2e3a0 0t0 TCP *:http-alt (LISTEN)
java 298 chanapps 18u IPv6 0x2e2ec50 0t0 TCP *:8009 (LISTEN)

And then, kill the process with "kill -9 298" command. Now, the tomcat recover!
