PI62352: DFHSM0002 A SEVERE ERROR (CODE X'0316') HAS OCCURRED IN DFHSMGF CAUSING ENTIRE CICS/PLEX REGIONS TO STALL

APAR status

• Closed as fixed if next.

Error description

• DFHSM0002 CQDAWR02 A severe error (code X'0316') has occurred in
  DFHSMGF causing entire CICS/Plex regions to stall.
  
  DFHEJOB performed the GETMAIN for OB_DATAB, and stored the
  resulting address in "buffer_ptr". The compiler has held this
  in register 11, but the value was not stored in the kernel stack
  storage. DFHEJOB then makes the remote file request for file
  DFHPIDIR.  This has been purged, and control has returned to
  the DFHEJOB recovery routine (EJOBREC). The code here attempts
  to release the OB_DATAB, but R11 no longer addresses the
  storage and is not reestablished.

  * PROBLEM DESCRIPTION: SM0002 severe error (code X'0316') for  *
  *                      FREEMAIN with comment OB_DATAB.         *

  ****************************************************************
  In the reporting customer's case, CICS was running as a web
  service provider with WS-AT enabled, and the WS-AT directory
  data set, DFHPIDIR, defined as remote.  During processing,
  an attempt was made to modify DFHPIDIR via DFHEJOB.
  DFHEJOB performed a GETMAIN with remark OB_DATAB and stored
  the resulting address in buffer_ptr.
  DFHEJOB then made a remote file request for DFHPIDIR,
  however this request was purged as a session could not be
  allocated on the remote system.  This caused an AAL8 abend.
  DFHEJOB's recovery routine was driven, which attempted to
  FREEMAIN the storage obtained previously.  However,
  addressability to buffer_ptr was not reestablished causing
  the FREEMAIN request to be made with an invalid address.
  This caused a SM0002 abend with code X'0316'.
