I developed a Python program for development of files necessary for my Network Dataset. I did my testing on a sample dataset (a small fraction of my actual dataset, same schema, etc.) to make sure everything is working as it is supposed to. When I move to utilizing my full dataset with over 92,000 line segments, the program crashes after about 5 to 7 minutes and goes to my finally statement where my cursors are being deleted. If I debug my program using printed arcpy.AddMessage statements, the stopping points have correct syntax and seem to be fine. As I mentioned, when I use my smaller dataset, everything runs smoothly. Anyone had this issue or know of what I could do to avoid it?
