PM87380: DFHSM0102 STORAGE VIOLATION WITH AN INCOMING CICS WEB SERVICE REQUEST. NAMESPAC STORAGE IS OVERLAID.

Obtain the fix for this APAR.

APAR status

• Closed as unreproducible.

Error description

• A web service call completes successfully, returning what
  appears to be a valid XML response to the requester.  However,
  each invocation of the transaction causes a storage violation.
  
  The trace shows:
  SM 030B SMGF  *EXC* - Storage_check_failed_on_freemain_request
  - FUNCTION(FREEMAIN) ADDRESS(1F3E79C8) REMARK(NAMESPAC)
  .
  and message:
  DFHSM0102 A storage violation (code X'030B') has been detected
            by module DFHSMGF
  .
  The NAMESPAC storage is used to build the associated namespaces
  with the request. The storage is getmained and freemained
  by DFHPISN.
  
  As a result the trailing checkzone (and following storage)
  are overlaid and the storage violation is detected during
  freemain at normal task termination.

  ****************************************************************
  * PROBLEM DESCRIPTION: DFHSM0102 storage violation due to a    *
  *                      null value for xmlns in an incoming Web *
  *                      Service request.                        *

  * RECOMMENDATION:                                              *
  ****************************************************************
  CICS is acting as a Web Service provider and receives a SOAP
  message with an envelope element that contains a null string
  for xmlns. For example:
  
  <env:Envelope env:encodingStyle="http://..........."
  xmlns:env="http://........"
  xmlns:xsd="http://........"
  xmlns:xsi="http://........" xmlns="">
  
  When DFHPISN copies the null string into the DFHWS-XMLNS
  container, the null length is interpreted as a length of 256
  bytes and results in a storage violation.
