Error description

• ABEND0C4-4 DGOVHMTC+1CC (at PK76667 level) on a 50EBF008 (Store)
  instruction.  R11 and R15 were both zeros.  A corrupt Snapshot
  History dataset led to the program check, but nonetheless
  Snapshot History Manager shouldn't ABEND when it tries to load
  a corrupt dataset.

  PROBLEM SUMMARY:
  During initialization of the Snapshot History Manager an already
  existing Snapshot History data set is read to build the table of
  contents. When corrupted data are read, the processing of the
  data can cause an ABEND S0C4 in load module DGOVHM00. The PE
  Server subtask tries to recover once and therefore restarts the
  Snapshot History Manager. The same corrupted data are read again
  and cause the same ABEND S0C4.
  
  PROBLEM CONCLUSION:
  When the Snapshot History data set is read, the data are checked
  for consistency before they are processed to build the table of
  contents. When inconsistencies are detected, the Snapshot
  History data set is renamed and a new Snapshot History data set
  is allocated to continue the collection of Snapshot History
  data.

Problem conclusion

• When the Snapshot History data set is read, the data are checked

  contents. When inconsistencies are detected, the Snapshot
  History data set is renamed and a new Snapshot History data set
  is allocated to continue the collection of Snapshot History
  data.

Temporary fix

• Stop the PE Server subtask, rename an inconsistent Snapshot
  History data set manually and restart the PE Server subtask.
