Error description

• The response returned for a Web Service Proxy service contains
  two SOAP envelopes with the fault information when all the
  following are true:
  
  - Probe is enabled.
  - Web Service Management (WSM) is enabled.
  - Web Services Management Agent's Buffer Mode is set to Buffer.
  - An error occurs during multi-step.
  
  The following is an example of a correct response:
  
  <soapenv:Envelope
  xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" >
      <soapenv:Body>
          <soapenv:Fault>
              <faultcode>0x03</faultcode>
              <faultstring>service error (TID
  4987687)</faultstring>
          </soapenv:Fault>
      </soapenv:Body>
  </soapenv:Envelope>
  
  The following is an example of a response returned where there
  is a double SOAP envelope with the fault information.
  
  <?xml version="1.0" encoding="UTF-8"?>
  <soapenv:Envelope
  xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
  <soapenv:Body>
  <soapenv:Fault><faultcode>0x04</faultcode>
  <faultstring>service error (TID 6401841)</faultstring>
  </soapenv:Fault>
  </soapenv:Body>
  </soapenv:Envelope>
  <?xml version="1.0" encoding="UTF-8"?>
  <soapenv:Envelope
  xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
  <soapenv:Body>
  <soapenv:Fault><faultcode>0x04</faultcode>
  <faultstring>service error (TID 6401841)</faultstring>
  </soapenv:Fault>
  </soapenv:Body>
  </soapenv:Envelope>
  

Local fix

• Use one of the following:
  
  1) disable Probe.
  2) set WSM Agent's Buffer Mode to "Discard". Note: Buffer mode
  is the recommended setting so only use this as a temporary
  workaround.
  3) disable WSM Agent.
  

Problem summary

• Affected is the use of Probe with Web Service Management
  (WSM) for a Web Service Proxy (WSP).
  
  If WSM is in "Buffer" mode, then a WSP SOAP response message
  is returned twice to the client.
  

Problem conclusion

• Fix is available in 5.0.0.11 and 6.0.0.3.
