revit exit error code

[Anonymous]

Does anyone know what the following code number means:

The program '[1328] Revit.exe' has exited with code -1073740791 (0xc0000409).

I'm trying to create an app that creates large number of families and whenever I get to the third family Revit crashes with this code.

Below are details from the journal:

Paul Hildebrandt,

Per the journal, sounds it caused by null document, you may need to check if family document was opened or closed successfully:" TransactionStateInterface constructed with NULL ADoc"

Besides, here are some best practices about Revit crash trouble shooting, they're worth reading:

Turns out there was an open SUBtransaction. For future reference the following doesn't through an exception but should:

Transaction tr = new Transaction(familyDocument, name);
 tr.Start();
SubTransaction str = new SubTransaction(familyDocument);
str.Start();
SubTransaction str = new SubTransaction(familyDocument);
str.Start();
str.Commit();
tr.Commit();

It seems to work for a couple loops but then Revit crashes.
