Used Gunicorn compound: ('0.0.0.0', 5000)

Question

I installed redis this afternoon and it caused several errors, so I uninstalled it, but this error persists when I launch the application with foreman start . Any ideas for 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

Check your processes. Perhaps you had an unclean exit, leaving the zombie process behind what was still working.

Answer 2

Just enter

 sudo fuser -k 5000/tcp 

. This will kill the entire process associated with port 5000.

Answer 3

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 4

After some searching on the Internet, it seems that the following command is best used. This kills all processes running on port 5000, and seems to work for me:

 kill `lsof -i :5000`
