This is likely caused by processing MPRANK20 (Subtype 6) MAR SMF records. Each MPRANK20 record can produce 1000+ CSV records. To resolve this issue:

  • Eliminate Subtype 6 record processing by specifying SUBTYPE='(1:5,7)'
  • Reduce Subtype 6 processing by specifying PROCMAX6='n'. This will cause Mainframe Analytics Interpreter to process only n Subtype 6 records.

Use RPTEACH to limit the messages by reporting only every nth MAR SMF record, such as RPTEACH='100' will report only every 100th record.
