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

Check your processes. You may have had an unclean exit, leaving a zombie'd process behind that's still running.
Just type
sudo fuser -k 5000/tcp
.This will kill all process associated with port 5000
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
After some searching on the web, it looks like the following command is the best to use. This kills all of the processes running on port 5000 and appeared to work for me:
kill `lsof -i :5000`
