Lately, in our app using IPP data services, we have encountered these errors from time to time.

<RestResponse xmlns="http://www.intuit.com/sb/cdm/v2">
  <Error RequestId="49f7926a9aa84cfc8289534801dee72d">
    <RequestName>ErrorRequest</RequestName>
    <ProcessedTime>2012-12-07T10:10:59+00:00</ProcessedTime>
    <ErrorCode>3001</ErrorCode>
    <ErrorDesc>message=This client has made too many consecutive requests over too short a period of time.  Please wait a short amount of time before attempting to submit again; errorCode=003001; statusCode=403; source=Throttling Policy</ErrorDesc>
  </Error>
</RestResponse>

Can't find any reference to a "Throttling Policy" or error code "3001" anywhere in the IPP documentation.

Any help is appreciated.
