Record limit when running Identity tool from PythonWin?

Hi guys,

Experienced GIS user here attempting to use PythonWin to run an identity process.

I seem to be running into a hard limit in the number of records generated in the output dataset.

Here's the background:-
I have a Python script which runs an identity operation between two datasets (both File Geodatabase feature classes inside the same geodatabase). It later performs a frequency, then pivot, on the output attribute table and later peforms some field calculations and field deletions in its final stages. I've tried and tested each section of this workflow in separate python scripts other than the identity command run at the first stage which was previously run inside ArcCatalog using the tool dialog box.

When I attempt to run this identity, the output dataset is partially generated, but appears to fail at, or close to, 220,000 records. (First attempt 220,000, second attempt 219,915).

Is there a hard limit on the number of records, or the file size, that can be generated when running the tool inside PythonWin? What else could be throwing it? Environment Settings? Scratch workspace? Is it the install of PythonWin?

Any suggestions gratefully received.
