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: 
Just type

```
sudo fuser -k 5000/tcp

```

.This will kill all process associated with port 5000
I know that if you're running MacOS, you may see "ControlCe" listed as the process. You can kill it, but it will just restart. After some searching, I found that the control center uses 5000 to listen for Airplay Receiver requests. You can disable this by System Preferences>Sharing>Airplay Receiver.
