  • Hi there,

    Likely what is happening is that your site is being hammered by wanna-be hackers who are trying to exploit the xmlrpc.php file, either to:

    1) test out passwords to try to login to your site, or

    2) use your site to launch a denial of service attack against another site.

    In either case, having the most up-to-date wordpress will not necessarily help your CPU/load problem. Nor will any plugin or purely wordpress-based solution, because no matter what, when xmlrpc.php is processed, PHP and MySQL etc. all get engaged which is resource intensive — even to return a wordpress-generated “not available” page.

    If you don’t use the Jetpack plugin, or any software or services which allow you to make posts to wordpress without logging into the dashboard (e.g. the IOS wordpress app) then your easiest option is just to block access to xmlrpc.php at the .htaccess level. This should bring your CPU load back down.

    You can block access by adding this code in .htaccess
    <Files “xmlrpc.php”>
    Order Deny,Allow
    Deny from all
    </Files>
