Apache startup Fail

You may sometimes encounter the following problem while starting apache server

====

[root@epsilon root]# /etc/init.d/httpd start
Starting httpd: (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
[FAILED]
====

To fix this run the following commands

#fuser -k -n tcp 80

That's all
