  In the DRF MAS (Master Address Space) Region, this problem
  (ABEND 0C4) is occurred in the module (FRXRLRA0) that
  determines if the log records read are necessary for the
  recovery process.
  If the subroutine "RVSortTableSearch" in this module is given
  the DB name and DD name from the information in the log record,
  it will identify the entry with the corresponding DB name from
  the database list (list of databases processed by DRF) and
  return the index of the database list (what number of the entry
  in the list). And, if the processed log record is not related
  to the database being recovered, zero (0) is returned as an
  index, but there is a bug in the subsequent processing, which
  inadvertently uses the index = 0 to look for an entry in the
  database list and then refer to an AREA outside the list.
  This time, ABEND S0C4 occurred because the address was an
  inaccessible location.
  In addition, depending on the usage status of storage of the
  entire system, ARAE that is mistakenly referenced may be able
  to access, but DRF will assume that the DB name is in the
  accessed location and compare it with the DB name in the log
  record, which will always be a mismatch, and subsequent
  processing will be bypassed. So, the problem does not occur.
  Therefore, this problem may or may not occur.
  

Problem conclusion

• FRXRLRA0 has been modified as follows.
  Bypass the process of checking the log if a database entry is
  not found in the recovery list.
