ArcGIS Server arcpy.mapping service hanging with ESRI basemap in mxd

TrentHardy

I am attempting to create an ArcGIS Server geoprocessing service that exports a map. The service runs a python script that uses the arcpy.mapping module to modify map extent, visible layers, layout elements, etc. of an existing mxd, then export the map. I have run into a problem, though, if the mxd has one of the ESRI hosted basemaps and I run the script through the service. If I run the script locally on the server, it works fine. If I run the script through the service, the code hangs when I call ListDataFrames.

mxDoc = arcpy.mapping.MapDocument(r'path\to\mxd')
setVisibleLayers(mxDoc)

def setVisibleLayers(mxDoc):
    dataFrame = arcpy.mapping.ListDataFrames(mxDoc)[0] #code hangs here

The code will sit here until the service reaches its timeout, at which point it logs an error, but then, strangely, it completes (usually, though not always). The job status shows failed, but the map gets exported. Below is the message output from ArcGIS Server:

Job ID: je327da53fea846d184109dd21edd85d4

What more is curious is that in a separate log where I have timestamps, the code will get to the ListDataFrames function quickly and sit there for the 5 minute service timeout. Then in a fraction of a second, the rest of the script will be logged and the map will be generated. This could be related to the logger, but the create timestamp of the exported file coincides with the timestamp in the log for when it says it exports.

Any ideas?

I'd love to see the code!
