            X'00000456' IN MODULE DFHWSATX

  The program check is due to DFHWSATX trying to link to DFHWSATR
  after DFHPIAT returned a disaster response.  DFHWSATX should not
  be trying to link in this case.

  ****************************************************************
  A webservice provider with Web Services Atomic Transactions
  (WS-AT) support is running in CICS.  A request to run that
  webservice is received from WebSphere.  Due to WS-AT being used
  CICS tries to register its interest in the transaction by
  sending a Register request to WebSphere.  WebSphere encounters
  an error while processing this request and returns a SOAP Fault
  to CICS.
  
  DFHPIAT is called to parse the response.  It is only looking
  for valid WS-AT messages so is unable to handle the SOAP Fault,
  returning an INVALID_MESSAGE response to its caller DFHWSATX.
  Due to a logic error in DFHWSATX,it attempts to link to
  DFHWSATR.  During the setting up of the DFHPGLE parameter list
  (used to issue the link) an ABENDS0C4 occurs at offset x'456'
  in DFHWSATX.
  
  Messages DFHPI0500, DFHPI0731 and DFHPI0507 will also be issued
  when this problem occurs.

Problem conclusion

• The logic error in DFHWSATX has been corrected so that it no
  longer attempts to link to DFHWSATR when a SOAP Fault is
  received.
