  ****************************************************************
  A CICS region had a PLT program at startup which suffered an
  abend 878/AKEB, because of short on storage in subpool 253. This
  resulted in an attempt to issue message DFHSI1580 via a WTOR.
  The message is issued by DFHMEME in a do loop because it needs
  to check for a valid reply. DFHMEME calls DFHSUWT to issue the
  WTOR, but the WTOR fails with a MVS D23 abend because of the
  short on storage condition. The D23 abend results in module
  DFHSUWT's recovery routine being driven, but it does not check
  for an abend of D23 and so does not set a short_on_storage
  response. Execution returns to DFHMEME as though all is well and
  because it appears as though no valid reply has been received
  the WTOR is issued again. This will loop forever.

Problem conclusion

• DFHSUWT's recovery routine has had a check for an abend D23
  added, which sets SUWT_DISASTER and SUWT_MVS_SHORT_ON_STORAGE.
  DFHMEME in INTERPRET_REPLY now sets MEME_DISASTER and
  MEME_NO_STORAGE_FOR_WTO if the call to DFHSUWT returns with
  SUWT_DISASTER and SUWT_MVS_SHORT_ON_STORAGE. It also sets
  ABLE_TO_WRITE_WTO to NO and REPLY_INVALID to NO.
  A system dump is also taken with dump code of
  ME_NO_MVS_WTOR_STORAGE_DUMPID.
  
  The CICS Messages and Codes manual for CICS Transaction
  Server for z/OS V3.2 (GC34-6827-01) will have the following
  added to the DFHMEnnnn messages section of the manual.
  
  DFHME0141 Message msgno not issued by module
            because MVS WTOR is short on storage
  
  Explanation:
  The message msgno cannot be written to the console
  because MVS is short on storage and the MVS WTOR has abended
  with abend code D23 while trying to issue the message. The
  message domain module which was attempting to issue the
  message is module.
  
  System action:
  An exception trace entry is written by the message domain and a
  dump is taken for dumpcode ME0141. Message DFHME0141 is written
  out in message text part of the dump summary instead of being
  sent to the console in order to avoid causing another abend.
  
  User response:
  Ensure you have enough storage for MVS or reduce the storage
  requirements of your CICS system below 16MB.
  Try decreasing the limits of the CICS dynamic storage
  areas (DSAs), DSALIM, or increasing the MVS region size.
  To increase the MVS region size you must terminate CICS and
  change the MVS JCL REGION parameter.
  For more information about how to do this,
  see the CICS Performance Guide.
