I hate for something like this to be my first post, but alas...

What are the chances of twiceler/cuill causing our site to basically come to it's knees?

Usually, everything is fine, but tonight, suddenly, mysqld is consuming a LOT of CPU time, and it's not going away. (In a dual proc setup, it's going from 98% to 160% cpu.) There were TONS of httpd procs/connections open. I initially thought it was an index problem, but once I saw this thread, I figured I'd look at the access logs, and sure enough... there were a LOT of twiceler requests in the timeframe of the slowdown.

For us, it's not a bandwidth issue, but a cpu issue. Has that been the case for anyone else or should I pursue my index theory?
