Well, my take on this is that you wouldn't see this problem if the file is corrupted. Instead, the entire page would simply fail to render unless you had the CFINCLUDE in a CFTRY/CFCATCH. The generated byte code has to be a fully-formed Java class that conforms to the Java Servlet API, and it seems to me to be unlikely that the class would be created correctly but just without your custom code. Again, I don't know enough about the internals of CF to guarantee this, but I do know a little bit about compilers and Java, and it seems unlikely. It would be useful if you could simply compare the bytecode size between "good" and "bad" versions of the same compiled class, if you could access those from the live server. They may be written to disk, in the cfclasses directory, if you have "Save cache files to disk" enabled in the CF Administrator. > > I've never seen this problem, even in many high-volume environments - some > > of which had their own problems. > > And it doesn't really make sense, given my (admittedly limited) knowledge > > of CF internals.

I guess what I'm getting at here is: you definitely have a problem. But I don't think your description of the cause of the problem is accurate at all, and you could easily go down a rabbit-hole here by focusing on what you imagine is the cause of the problem, rather than the problem itself. The basic description of the problem is that you're not getting the output under load that you get without load, right? What happens if you block incoming traffic to the server, stop and restart the CF service, and rerun the same pages, with "Save cache files to disk" enabled?

You could certainly try to just deploy compiled classes and see what happens. It's generally a good thing to do in production anyway. Another approach you could try is to force the server to precompile everything by running a test script that generates an HTTP request for each CF file before you open access to users.
