SOVED apache already in use error

hello.

I just ran a````
/etc/init.d/apache2 restart

and I'm getting this error

Restarting web server: apache2(98)Address already in use: makesock: could not bind to address [::]:80 (98)Address already in use: makesock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
Action 'start' failed.
The Apache error log may have more information.
failed!

Then I ran````
netstat -lnp | grep :80

and then this was the output

tcp6       0      0 :::80                   :::*                    LISTEN      2057/apache2 

I don't know what that means. Some help would be very much appreciated.

Thanks,

John
