    This morning, I noticed a site being unresponsive with the following error that was repeated countless times before the actual site loaded. It took 3-4 minutes to load the entire page. While this was happening, I checked the proc and noticed index.php wp-cron.php tripping out. Run away process tanked the site. Not sure, but I assume the submission form was getting hit by a bot.

    I am wondering if the memory leak is caused by the cron job, “Every 24 hours the plugin runs a formula to calculate the page rank of every website from all the categories.”

    Perhaps I should rip this out and see if it runs stable.

    So yeah, just a heads up, I went through the plugin and gave it an ethnic cleansing of everything to do with PageRank. It seemed to overburden the server and locked up the process. Running through tests right now. I’m not entirely why it was taking up 198% proc but it pulled aggro harder than a DayZ Zombie.
