I have seen this before.

Look at your

/etc/logrotate.d/apache


/var/log/httpd/access_log {
    daily
    prerotate
        rm -rf /tmp/.logrotate_apache_access >/dev/null 2>&1
        cp /var/log/httpd/access_log /tmp/.logrotate_apache_access 
 >/dev/null 2>&1
    endscript
    missingok
    notifempty
    sharedscripts
    postrotate
        /bin/kill -HUP `cat /var/run/httpd.pid 2>/dev/null` 2> 
/dev/null || true
        /usr/local/sbin/split_logs web < /tmp/.logrotate_apache_access
        rm -f /tmp/.logrotate_apache_access >/dev/null 2>&1
        /usr/bin/webalizer.pl
    endscript
}

That is what you want to look at.
