Help needed in diagnosing http 500 and intermittend ORA-44003 problems.

Question

We have a client that has some problems with a particular page in our Apex application. The problems only occur in this one application instance for this particular client.
The problem concerns a report with a form.
1) When creating a new record the form page is called with no parameters and a cleared cache. This leads to a http 500 message.
2) When opening the form for an existing record the form page is called with the records ID. This usually works but every now and then we get a "ORA-44003 Invalid SQL name" error message. When trying the same record immediately again it does work. Data is fetched using automatic row fetch.
We are not sure if this problem is data related, listener related, or something else entirely.
We work with Apex 4.02.007 and Apex listener 1.1.2.131.15.23 running in OC4J. Database is 10.2.0.5
The application is installed in an Apex runtime environment.
What can we do to find out more about the http 500 message? What logfile would there be? What parameters to set to get more useful log info?

Solved in Apex Listener 1.1.3Could you perhaps elaborate on the solution? Maybe someone desperate and frantic might come across this thread one day and might need the assistance you weren't able to get the first time around!
Even if it's just down to buggy application code (i.e. self-inflicted! :-) ), it would be worth knowing how you investigated the issue, how you were able to discover the source of the error (given you were encountering something entirely different at first) and lastly how eventually solved it.
