Question

HTTP 500 Error - inplace of Debug Info.

I have CF8 Developer Edition installed on a Win XP Home platform.

Normal debug information displayed when a problem occurs is being replaced occasionaly by the standard MSIE 7.0 HTTP500 Error page - which contains no debug information. Any ideas whats causing MSIE to substitute the page for the normal (very useful) debug information?

    In a CF context, this means the CF (or, more likely, JRun) encountered a
    terminal error whilst processing the request. Basically the CF thread
    processing the request crashed. You don't get the debug, because CF
    stopped servicing the request.

    It'll - almost certainly - be down to an error in your code.

    These are often quite fun to track down; but look for endless loops in
    which large amounts of memory are allocated, or out-of-control recursions,
    and that sort of thing.

    Yup - quite fun - those are the words I was looking for earlier :)

    I've resorted to putting cfexit's in the code to try and stop processing ahead of where the problematic code may exist. So far the problems are not limited to a single type of error - I've had one instance where the field declared in an insert statement didn't match the field in the db and a couple of others that dealt with string manipulations.

    Makes a lot of sense that the jrun engine is crashing and preventing the display of the error message.

    Is there a log file somewhere that may be capturing the error information just prior to the crash?

    quite fun indeed...

    Thanks for the help.

    assuming you've enabled debugging with your ip address?
