I am unioning a fc with ~45k features, and am getting this error, even after repairing and checking geometry until no errors are found. I know this error has come up before, but doesn't seem to ever get addressed with any seriousness. Polygons with under 100k features are not so big that I'd expect machine failure, and if the error is not geometrical, why does it say it is? How do I fix this "duplicate segment", and what does it mean?
In short, PLEASE alter these error messages so that they are not maddeningly cryptic and actually can point me to a solution. Thank you.
