How did you narrow it down to the Bing bot? 

Curious form an IT web host POV.

Thanks

Library.php tripped the CPU limit, so I grabbed the raw server access logs for July and reviewed the 12 hours before we were nailed. BingBot declares itself via UserAgent when it makes requests and 95%+ of the requests to Library.php during the period in question were BingBot crawling from page to page and initiating scores of DB connections.

From there a simple update to Robots.txt took care of it. Googling around, I'm not the first person to be psuedo-DDoSd by BingBot...

Another fine feature brought to you by the world's new super-villian, Bill Gates...
