haproxy does not stop when using service/invoke-rc.d

[Hans van den Bogert]

When trying to stop haproxy using

sudo service haproxy stop

  or

sudo invoke-rc.d haproxy stop

The tools exit with status 0, but haproxy is still running.

Example:

    sudo invoke-rc.d haproxy start
 * Starting haproxy haproxy [ OK ]
be@fe2-lb1-test:~$ echo $?
0
be@fe2-lb1-test:~$ sudo invoke-rc.d haproxy stop
 * Stopping haproxy haproxy [ OK ]
be@fe2-lb1-test:~$ echo $?
0
be@fe2-lb1-test:~$ ps aux |grep haproxy
