[ale] [HELP] - errors rotating logs

I've come to the list with this problem before:

Here is the answer I received:

I thought it worked, but I just got errors again.  Here is the mail I
received to root:

errors occurred while rotating /var/log/httpd/access_log

httpd: no process killed
error running postrotate script

I also looked at the /etc/logrotate.d/apache file as suggested before.
It shows the following for /var/log/httpd/access_log:

/var/log/httpd/access_log {
    postrotate
        /usr/bin/killall -HUP httpd
    endscript
}

Can someone point me in the right direction to finding out what's
wrong?  I have a couple of theories, but I don't know if my logic is
sound.

First, is postrotate a script that I can find on my system somewhere
or do the following lines denote it AS the postrotate script itself?
	    postrotate
                /usr/bin/killall -HUP httpd
    	    endscript

If this is the script definition, how can I run it from the command
line to see what errors will happen?  Also, if this is the script,
what is it trying to kill?  Is it trying to kill all processes being
invoked via httpd?

Lastly, am I getting errors rotating the logs because they are set to
rotate and keep four weeks worth of log files and after that time I
have to delete logs before it can put new ones?  I doubt this is the
case.  Because what would be the point of having automated log
rotation if it couldn't just overwrite the logs that were already
there?  Of course I'm not sure though.

Any help is appreciated.

Thanks,

Rick
