问题
I'm assuming it was because the process didn't close properly and so is still running. But using top or ps I can't find it. Is there a way to find where it's running, or to have it force reopen the port?
回答1:
try sudo netstat -lpn to see what ports are being listened to, and what processes are listening.
回答2:
In the case of an old instance of Spork running you may use this command:
pkill -f spork
