Viewer 3.2 Server 10.1 Export Web Map Task Error 2032

[LuciHawkins]

We have been using Flexviewer 3.2 to serve out our services and everything has been working fine.  We were using an older print widget and we decided to try and take advantage of the new advanced printing capabilities on our ArcGIS Server 10.1 SP1.  We entered our URL: 

http://fwbgis/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task

and we have also tried:

http://fwbgis:6080/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task

Both URLs work in the print widget when we view our flex app in either Firefox or IE.  The problem is that we get the following error pretty often, more often in IE than Firefox.  It seems like the more we display on the map the more printing fails.
 

Error executing print task:

[RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error. URL: http://fwbgis:6080/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task/execute"]. URL: http://fwbgis:6080/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task/execute"]

We added the .swz to the mime types in IIS.  We have our config.xml file setup properly.  Has anyone else ran across this type of behavior?

Thanks,

Luci
