You could also do "sudo netstat -tulpen" if you're on linux or sockstat -l on
freebsd to see what other process has this port open.

It could also be that something crashed and the OS has not yet "garbage
collected" that port, so maybe try waiting a few minutes and then try again if
the netstat command doesn't show anything..
