  ****************************************************************
  If a system abend occurs in module CSQWVZSS while capturing SMF
  statistics data, the recovery routine may not correctly
  establish its base registers before performing recovery
  processing. This may result in an S0C4 abend occurring and
  masking the true cause of the underlying abend.
  

Problem conclusion

• Processing has been amended to ensure that recovery processing
  establishes its base registers correctly and the underlying
  abend is correctly reported.
