I had a somewhat similar issue that I am just beginning to research.
We just upgraded to CF Enterprise 4.5 from CF Pro on NT 4.0/IIS 4.0.
One of our pages allows you to download a screensaver program. This
page was returning a CGI error every time it was run and keeping the
memory locked on the Web server for this process. Every time a new
request to download this screensaver was made, a new NT Process was
created it for it, the page would error, and the process would not
be released. Thus, it was eating up all of our memory.
I am not sure if this page is using CFHTTP but the error led me
to believe that it was. I am using the CFHTTP patch from the
4.5 Hot fixes.
The second thing that I have noticed with 4.5 is with CFFILE. I
have a process that generates about 500K - 600K files at a time.
We use these files to send out newsletters instead of using CFMAIL.
The problem is that in 4.0.1 it takes about 6 minutes to generate
10K files while in 4.5 Enterprise it takes about 3 hours to generate
10K files. If I downgrade the server to 4.0.1 it goes back to taking
6 minutes. I am curios to find out if anyone else has run into a
similar issue.
Thanks -

As I understand it, each CFHTTP request requires a separate thread. CF only
creates a set number of threads when the service is started - the number of
simultaneous requests that you put in the Settings page of the CF
Administrator. If that's set to five, which is a common default, and your
one page requires twenty, there are likely to be problems.
