Troubleshooting VNC Connection error

So I'm back out to work after a nice vacation, so I should have seen this coming, right?

When attempting to connect to my VNC Server from my client, a nice error message popped up.
Unable to connect to server.
I managed to ssh into the server, but the VNC Server refused to restart:

[myuser@xxxxxx tmp]# service vncserver restart
Shutting down VNC server: 3:myuser                         [FAILED]
Starting VNC server: 3:myuser
Warning: xxx.xxx.xxx:3 is taken because of /tmp/.X3-lock
Remove this file if there is no X server xxx.xxx.xxx.xxx:3
A VNC server is already running as :3                         [FAILED]







Long story short, I had to delete the lockfile and socket in order to be able restart the VNC Server.

0. Login as root/sudo
1. Remove lock file and socket
rm -rf /tmp/.X3-lock
rm -rf /tmp/.X11-unix/X3

2. Restart vnc service
service vncserver restart
