Processes Will Not Close In cPanel

I'm having an issues with one of my processes not closing properly on my site. In turn, it clogs up the server I'm on and cause the site to crash with a relatively small amount of traffic.

The process I'm having an issue with is /usr/bin/php /home3/davejon/public_html/index.php



The coding for Index looks like this:

Code:

<?php
/**
 * Front to the WordPress application. This file doesn't do anything, but loads
 * wp-blog-header.php which does and tells WordPress to load the theme.
 *
 * @package WordPress
 */

/**
 * Tells WordPress to load the WordPress theme and output it.
 *
 * @var bool
 */
define('WP_USE_THEMES', true);

/** Loads the WordPress Environment and Template */
require( dirname( __FILE__ ) . '/wp-blog-header.php' );

I'm new to all of this so any help on this issue would be greatly appreciated.
