Excessive SPU | WordPress.org

The jetpack search is generating excessive cpu (> 50%, sustained 90%) load. These messages started appearing in the nginx access log. Here’s an excerpt from the most recent activation. The source address is the server’s. In otherwords, it’s a loopback query being generated at sustained rate. At first glance, it looked like a DoS.

Looking for a suggestion. Thanks!
