It may be the fact that you're now using CFHTTP instead of CFX_HTTP. Many of
us have experienced similiar problems with CFHTTP -- do you use it quite
heavily on your site? I've switched all of my CFHTTP calls over to ASPHTTP
(www.serverobjects.com), a COM object you can access with CFOBJECT. There's
another one out there called ASPTEAR that works well (I hear).

Chris
