My server's error log (in cPanel) has an entry for every single time a PHP page is loaded that looks like this (where 'username' has been substituted for my actual username):

[2012-06-09 09:02:07]: info: [usr/grp]: username/username cmd: /home/username/public_html/error.php php: /usr/local/php53/bin/php

I know it's only an 'info' message but it's filling up my error log. It can't be related to the content of my PHP files because it even happens when I load a page with this as its content:

<?php phpinfo(); ?>

Any ideas on what it means or if I can get rid of it?
