  received shortly after CICS has recovered from a SOS situation.
  
  Abend occured after a BASR from DFHMQTRU +x42A70'. Reg 15
  contains Msg handle create routine address (CSQBCRMH) loaded
  from CLOC +x'140'.
  
  CSQBCRMH was flushed after SOS but CLOC is never updated to

  ****************************************************************
  DFHMQCON loads programs CSQBCRMH and CSQBPAPI for exploitation
  of IBM WebSphere MQ V7 functionality.  The ENTRY addresses are
  stored in the CLOC and are referenced by DFHMQTRU when it makes
  a call to one of these programs.
  However if CICS goes SOS, CSQBCRMH and CSQBPAPI may be flushed
  as they are loaded without the HOLD option specified.  The CLOC
  is not updated in this case and as a consequence if DFHMQTRU
  issues a call to one of these programs an 0C1 abend occurs.

Problem conclusion

• UK52619 UK57403
  The EXEC CICS LOAD commands in DFHMQCON, used to load CSQBCRMH
  and CSQBPAPI, have been modified to include the HOLD option.
  With this option specified the programs now remain in storage
  until explicitly released and will not be flushed in the event
  of CICS becoming SOS.
