The only way I seem to be able to correct this is by restarting the server.
I can restart Apache only right after the restart of the server. But it seems to happen after a little bit of time..
I am so confused as to who it is doing this...

Thank you for your help.

what changes have you made recently to apache httpd.conf?
can you provide the follwoing info.?
operating system, version.
number of domains hosted. ie: 1 or more
is your website popular? heavy traffic?

I see, this indicates that apache is not shutting down completely before starting again

when you try to restart apache next time and get the same error
try to execute the command

netstat -lnp | grep '0.0.0.0:80'

and then kill that process id
example:
kill -9 22411
try to restart apache and see if it restarts successfully
