Apache Error : Address already in use: make_sock: could not bind to address

You may receive the below error while Restarting the Apache.

Error:
Address already in use: make_sock: could not bind to address [::]:80
no listening sockets available, shutting down

Solution:

# netstat -ltnp | grep ':80' 
tcp        0      0 :::80    :::*     LISTEN      11628/httpd

# kill -9 11628
# /etc/init.d/httpd restart

Now the httpd should works fine.
