Ok after further testing, once the FH 'bulk_file' => bless( \*{'Fh::fh00001Giant.odt'}, 'Fh' ) is in the cgi session file, things go astray. As stated in my update, which probably should have gone down here, I have tried to clear the 'bulk_upload' FH from the session. I also tried this in the post run with no success.

Does anyone know of the correct way to delete the FH from the session or a way to force clean up after a "clear"?

Thanks
