Geoprocessor HRESULT problem

I am trying to run a "simple" Getis-Ord analysis on a feature class using the Geoprocessor object, and can't seem to figure out what the problem is.  I am getting the dreaded HRESULT E_FAIL error.  I also have dissolved buffer, and explode multi-part geoprocessor methods that run without problem.

public static void PerformGetisOrdAnalysis(this Geoprocessor gp, string inFeature, string field, string outFeature)
            HotSpots getisOrd = new HotSpots();
            getisOrd.Input_Feature_Class = DatabaseUtils._scratchWorkspace.OpenFeatureClass(inFeature); // input feature class
            getisOrd.Input_Field = field;
            getisOrd.Output_Feature_Class = DatabaseUtils.FGDBPath + "\\" + outFeature; // location of output feature class
            getisOrd.Conceptualization_of_Spatial_Relationships = "INVERSE_DISTANCE";
            getisOrd.Distance_Method = "EUCLIDEAN_DISTANCE";
            getisOrd.Standardization = "NONE";
            getisOrd.Distance_Band_or_Threshold_Distance = 200;
            gp.Execute(getisOrd, null);
            if (gp.MessageCount > 0)
                for (int Count = 0; Count <= gp.MessageCount - 1; Count++)

Has anyone used this tool before with ArcObjects?  It just fails on Execute with no error.  I've tried many variations of the parameters, but it tells me nothing.
