rez_serialize_post causing 502 server error

I have a shortcode in the wp-content of this post: http://bernards.local/careers/employment/. This page loads fine.

If I request the parent page (http://bernards.local/careers/) it will cause a 502 error and not load the page.

The first line in the foreach() loop seems to cause the error.

        foreach($pages as $parent_page) {
            $output[$index] = apply_filters('rez_serialize_post', $parent_page);  // This breaks the server
            $output[$index]['related']['children'] = array();

            // Now add children
            $args = array(
                'post_type'        => 'page',
                'orderby'          => 'menu_order',
                'posts_per_page'   => -1,
                'post_parent'      => $parent_page->ID,
                'order'            => 'ASC'
            );
            $children = get_posts($args);
            foreach($children as $child) {
                $output[$index]['related']['children'][] = apply_filters('rez_serialize_post', $child); // This breaks the server
            }
            $index++;
        }

Finding out that even when visiting http://bernards.local/careers/ the shortcode is running, so this is generating an infinite loop.

[drewbaker]

So the issue was that the shortcode was running on any parent URL, and because the shortcode did a get children loop off global $post, it would become an infinite loop.

Not sure exactly why it's running the shortcode on every URL (and using the $post that goes with that URL), I suspect because apply_filters('the_content', $target_post->post_content) line in rez_serialize_post is opening up the shortcodes, which is causing the loop? Or perhaps its the use of setup_postdata() in rez_serialize_post? That is actually probably not needed anyway...
