haproxy unable to bind socket

After confguring haproxy and when you start the haproxy services as you can find in
Install and Configure HAProxy on CentOS/RHEL 5/6, you might encounter the following error.
Starting haproxy: [WARNING] 265/233231 (20638) : config : log format ignored for proxy 'load-balancer-node' since it has no log address.
[ALERT] 265/233231 (20638) : Starting proxy load-balancer-node: cannot bind socket

To check whether what other services are listening to the port, do the following
# netstat -anop | grep ":3389"
tcp        0      0      *                   LISTEN      20606/xrdp          off (0.00/0/0)

Stop the listening services
# service xrdp stop

Start the haproxy service
# service haproxy

You should not encounter any error now.                                                           [  OK  ]
