RPC Fault faultString="HTTP request error"

Hi
I have a geoprocessing service(AGS Server 10.1) that flex viewer (3.3) return this error for it:

RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032"]. URL: http://localhost:6080/arcgis/rest/services/mytoolls/GPServer/mytoolls/jobs/j00d71b79556f44088fad1356ee74a91d?%5Fts=1372323386300&f=json"]


I checked every thing.
What should I do?
Regards
