When you run arcpy.JSON_to_features using the attached json file. It just crashes python. I am using 10.3.
The json is actually the result of this 1=1 query. Click the link and save the output to a .json file.
If you use ArcMap and try to run the JSON to features tool with the attached JSON, then it would just keep running forever and ever.
I tried with other services on sampleserver6. It works on all other services. Its just this one its crashing on.
I am seeing that it crashes on all layers in this mapservice:
