Gunicorn Connection in Use: ('0.0.0.0', 5000)
Solution 1
Check your processes. You may have had an unclean exit, leaving a zombie'd process behind that's still running.
Solution 2
Just type
sudo fuser -k 5000/tcp
.This will kill all process associated with port 5000
Solution 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
Solution 4
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`
Source (although a bit more shady than I prefer)
Solution 5
Find the orphaned process:
ps -ax |grep gunicorn
11111 ?? 0:03.44 /usr/local/Cellar/python/3.7.4/Frameworks/Python.framework/Versions/3.7/Resources/Python.app/Contents/MacOS/Python /usr/local/bin/gunicorn -b :5000 main:app
Locate the Process ID (the number in the first column of the results)
kill 11111
Replace 11111 with the Process ID

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)
