We are having a issue where ColdFusion maxes out the CPU. It will remain that way until we restart ColdFusion. This has happened a few times before but the last time it completely hung and displayed the site wide timeout page as plain text exposing the ColdFusion code.
We did update the web server connectors after installing update 12. I've looked in so many log files and seen so many things using windows process monitor that I'm not sure if I missing something important or focusing on the wrong erros.
This post on the forums describes what we have been dealing with.
