I can try. The data size isn't big, but the scripts that run against it are,
and are dependent on our development enviornment. What I'll have to do is pull
out the db portion of the app and see if I can simplify it - might work. The
app is a test system that runs against our big storage libraries.

Is there anything I might be able to do (without the test case) that would help
figure out what's happening?

Cheers,
Rob
