I'm attempting to Dissolve a feature class, which contains almost 2 million features, using a stand alone script. However the script gives up before the dissolve is complete and the output feature class covers approx 75% of the input features - there is no error.
When I perform the same dissolve in ArcMap, using either the tool GUI or the python window, it completes fully. So what gives? Is there something I can do to stop the stand alone script finishing early? - it is intended to become a longer script but at the moment it's set up to just perform the dissolve using all default settings.
