    ****************************************************************
    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.
