Gunicorn Connection in Use: ('0.0.0.0', 5000)

Question

I installed redis this afternoon and it caused a few errors, so I uninstalled it but this error is persisting when I launch the app with foreman start. Any ideas on a fix?

foreman start
22:46:26 web.1  | started with pid 1727
22:46:26 web.1  | 2013-05-25 22:46:26 [1727] [INFO] Starting gunicorn 0.17.4
22:46:26 web.1  | 2013-05-25 22:46:26 [1727] [ERROR] Connection in use: ('0.0.0.0', 5000)

Answer 1

Just type

sudo fuser -k 5000/tcp

.This will kill all process associated with port 5000

Answer 2

This should do the trick for you:

kill -9 $(lsof -i:5000 -t) 2> /dev/null

where 5000 is the port you want to kill

Answer 3

Check your processes. You may have had an unclean exit, leaving a zombie'd process behind that's still running.
