• ABEND 0C4-00000010 was issued in DSNXGRDS.DSNXRLPT because Db2
  is incorrectly calculating the number of parallel child tasks at
  runtime for this query, which involving page range partitioning
  where we are partitioning on a partitioned inner table, and not
  all parts are qualified.

  query parallelism.  The abend can occur on a query
  involving page range partitioning where Db2 is
  partitioning on a partitioned inner table, and not all parts
  are qualified.  The abend occurs due to Db2 incorrectly
  setting the number of parallel child tasks.
