 * Hey guys!
 * I really love this plugin, I really do!!
 * Only problem is that it caused a massive surge in IO and CPU load, basically 
   making the website so frantically busy that no humans could access it. I wasn’t
   able to fix it until I deleted the plugin directly off the server.
 * It wasn’t always like this though. For months, it worked beautifully. But at 
   4:56 AM 4 days ago, it went haywire. I wasn’t awake or working on the website,
   and none of my helpers were either.
 * Something automated happened at that point in time that made your plugin break
   my website.
 * It wasn’t the only plugin to break either. An old plugin I’d been using to generate
   a site-map also broke and caused the same ruckus. The two of them together really
   insured that no humans could access the website.
 * So, I think that something updated about WordPress itself that broke everything.
 * You guys likely know a hell of a lot more than I do about what could have happened
   to cause this. I deleted the plugin so my website is working again, but I don’t
   want to add it back until you guys have solved this mystery.
 * Thanks,
 * Fiona

 * Don’t think that was caused by the plugin (or we would have heard lots of reports
   by now). If there wasn’t a WP auto-update at that precise time (you should have
   received an email telling you WP was updated right after it was done), perhaps
   there was an attempt to compromise your site or look for compromised files? Maybe
   your web hosting company can tell you more about what caused the CPU load like
   specific files accessed, where the connection were coming from, etc.
