Error description

• CICS is processing an inbound SOAP request when this problem
  happens. The problem requires a SOAP header handler program be
  active and for a context switch to take place. During the
  SEND-RESPONSE phase of the PIPELINE, the SOAP header handler
  program has to issue EXEC CICS SOAPFAULT CREATE. This causes
  DFHPISN to drive the header programs again for HANDLER-ERROR.
  DFHPISH is called to manage this process. However, its list of
  programs to call was freed at the end of the SEND-RESPONSE
  phase and so it needs to be reconstructed. This process
  requires the data from the DFHPARSE-OUTPUT container. The SET
  data for the container has been freed when the container got
  re-imported after running the user task. Depending on whether
  the SET storage got reused will effect the error that occurs
  in DFHPISN.

  ****************************************************************
  A provider PIPELINE with at least 1 SOAP header handler is
  installed in CICS.  A SOAP message is received by CICS and
  passed to this PIPELINE for processing.
  
  DFHPISN parses the SOAP message and the output from the
  parser is placed in the DFHPARSE-OUTPUT container.  DFHPISN
  accesses the output using it's address pointer.References to
  data within the pointer are kept in the PISN block for this
  request.
  
  DFHPISH is called to invoke the header handler programs.  To do
  this a program_list structure is created using information from
  the PISN block, which ultimately refers to the DFHPARSE-OUTPUT
  container.
  
  One of the handler programs has caused a context switch to
  occur.  This means that the apphandler (DFHPITP) runs in a
  separate task managed by request streams.  This process causes
  the current channel to be exported and sent to the new task.
  On completion the original containers on the channel are
  deleted and a the updated channel is imported.  During the
  deletion process the DFHPARSE-OUTPUT was freemained.
  
  DFHPISH is called to invoke the header handler programs again.
  It uses the program_list structure created earlier.  One of the
  header handler programs generates a SOAP Fault.  When DFHPISH
  completes, the program_list structure is deleted.
  
  Due to the SOAP Fault being created, DFHPISH is called again
  so that the header programs can be notified of the error.  The
  program_list structure was deleted so a new one is required.
  This is built using the PISN block for this request which still
  contains references to data in the earliest DFHPARSE-OUTPUT.
  The container doesn't exist any more.The results are
  unpredictable and depend on whether the area of storage has
  been reused or not.  In this case a DFHPI0002 message and dump
  were issued.
  

Problem conclusion

• DFHPISH and DFHPISN have been changed to ensure the
  DFHPARSE-OUTPUT and program_list structures exist for the
  lifetime of the SOAP handler.
