Publishing a synchronous python script as a geoprocessing service

BenStewart — Fri, 18 May 2012 11:45:35 GMT

This might belong in the Server forums, but I thought I would try here first.

I have a python script that performs a basic Zonal Statistics as Table. I publish it as a GP service, however, when the tool is published as synchronous tool, it hangs, despite the fact the it successfully runs the tool (I can see the output on the server). When I run it asynchronously, it works fine. Any ideas?

chosenFile = arcpy.GetParameterAsText(1)

    chosenFile = "GDP"
