 * My ISP has reported excessive CPU utilization, owing to the process
 * wp-admin/admin-ajax.php
 * I first suspected excessive heartbeat, but installing the plugin that stops that
   did not make any difference.
 * I disabled your Limit Attempts plugin and then monitored the process list. The
   wp-admin/admin-ajax.php process did not run and the CPU utilization returned 
   to normal.

 * Hi rvbinder,
 * Our Limit Attempts plugin cannot load wp-admin/admin-ajax.php process, as it 
   uses ajax function only on the plugin settings page to restore default error 
   notifications and email messages. This function goes off only when “Restore default
   message” and “Restore default subject” buttons are clicked on.
