I have a point density geoprocessing service. I successfully created a GPFeatureRecordSetLayer JSON from a list of point features from QUERY. When I run the tool after first creating the service, it runs fine. Subsequent runs fail however. I believe this is due the fact that the output raster name already exists, but I am not sure. Additionally the raster is stored in scratch.gdb in the Job folder. Since there are multiple jobs, the raster name shouldn't be an issue. How do I solve this problem?
