We're on CF 10 Standard in a virtualized Windows 2008 Datacenter environment working on this really old CF application. For some reason, requesting the application results in 1 of the 3 following results seemingly randomly:
Using the Web Developer Toolbar, I can see that when the pages don't load fully, there is either an Error 101 (ERR_CONNECTION_RESET) or an Error 103 (ERR_CONNECTION_ABORT). To troubleshoot, I disabled the application.cfc (by renaming to .old) and took the code that was generated on a successful page load and placed it into a test.cfm, which I called. Doing this and calling the test.cfm page results in the page display all the content every single time, whatsoever.
Random is a hard thing to troubleshoot. What would cause CF (or IIS, or anything else on the network) to randomly cut connections like this?
The only thing I could think of is some request-filter that maybe prevents too many requests at the same time, but having checked that area in IIS, I can see no such setting is implemented.
