Restarting sw-cp-server never works

For a while now I've noticed that on Plesk 12 the sw-cp-server init scripts can never restart the sw-cp-server properly. I have to manually kill the master process then restart it:

Code:
# /etc/init.d/sw-cp-server restart

Why is there no response to this? It is not only a valid question but a problem that many people are facing. See below for example:

[root@webhost1 certificates]# service sw-cp-server restart

I fixed my own problem and will post the fix here for the OP.

On the command line type lsof -i 8443

This will return something like this:

[root@webhost1 certificates]# lsof -i :8443
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
sw-cp-ser 8627 root 9u IPv4 36562572 0t0 TCP *:pcsync-https (LISTEN)

Then kill -9 8627 8628
Then service sw-cp-server restart

That should fix your problem.
