I've been using a Python script to try and copy a dataset from ArcSDE 10.1 Oracle 11g database to a local 10.1 file geodatabase. The dataset contains 10,997,525 records. Using the arcpy.CopyFeatures_management tool I'm not able to copy the entire dataset across. My first attempt copied 8,568,846 records and my second attempt copied 9,411,659 records. There are no error messages reported so it looks like it has copied the entire dataset correctly. This is a polygon dataset I'm trying to copy. I do have a line dataset with more records (30 million +) that copies all the records across correctly.
I've also tried using the ArcToolbox tool 'Copy Features' and it has a similar problem.
