Multiple requests resulting in 502 errors

Just in the past day or so we went from zero errors to our WPEngine server being bombarded by requests from the Ajax Load More plugin resulting in our site constantly crashing with 502 errors. We checked with WPEngine and it is not their servers but is stemming from the requests.

Here is what we received when communicating with our host:

“Here are the errors and amount of ajax calls I told you I would send over in regards to the specific plugin.

Here is the shortcode I am using for the template page:
echo do_shortcode('[ajax_load_more post_type="post" category="news" posts_per_page="6" scroll="false" transition="fade" button_label=""]');

I can also send you the error log if you like.

Any help would be great. Thanks!
