difference between indesign server 5.5 and indesign server 6

org.apache.axis.client.call.class file in axis.jar

private void invokeEngine(MessageContext msgContext) throws AxisFault {

       this.service.getEngine().invoke(msgContext);

        ........

        throw ((SOAPFault) respBody).getFault();

    }

in 5.5,all are working properly.

in 6,the marked red code executed 10s.

Both call SOAP1.1.
