Hi everyone,

I'm trying to print a map made using the ArcGIS JavaScript API.  I'm using version 3.11 of the API with ArcGIS Server 10.1.  Here's my test page (which works with very simple KML layers) http://censusdemo.ssmic.com/printTest.html :

    }
    function printError(error) {
      alert(error);
    }
   }
  );
</script>
</html>

If I replace line 99 with the line above it ( which is link to a much more complex KML layer) then my GP Task times out after 10 minutes.

I've set up the PrintTools on my GeoProcessing server to be Asynchronous and have set the max records to 500,000 as seen here:

Utilities/PrintingTools (GPServer)

The only reason I can think of for why it times out this way is that the kml file in line 99 is 780KB in size and the KML file that causes the timeout is 4,742KB in size.

What am I doing wrong here?
