Incremental Spatial Autocorrelation Model Failing

I've been trying to determine a proper distance band for my data.  I have 461,565 points (throughout New York State) and my input field is an aggregated field that has a sum of almost 8 million.  Every time I run the Incremental Spatial Autocorrelation script, as well as the Spatial Autocorrelation Script (Morans I), it fails with a "<type 'exceptions.MemoryError'>:". 

I'm working with a projected data set and the data frame has the matching projection (NAD 1983 UTM Zone 18N) and I when I enter thresholds I make sure I am referring to meters.  Is there a limit to the size of the input features?  Should I close out other applications when running the script?  I am working with files in a geodatabase, I exported the file to a shapefile and created a .SWM and used that in the Spatial Autorcorrelation Script and that worked but I would need to run the script a bunch of times to determine the best distance.  I'm running the Incremental Spatial Autocorrelation script right now on the shapefile and it seems to be running better, but slowly.
