PL04177: WHEN RUNNING RFG WITH TEST=Y 1 MILLION+ BLANK LINES ARE PRODUCED IN THE TRACE OUTPUT.

APAR status

• Closed as program error.

Error description

• CUSTOMER RAN AN RFG PROGRAM WITH TEST=Y IN THE COMMAND. IN THE
  CONTROL TRACE 1 MILLION+ BLANK LINES WERE GENERATED. CUSTOMER
  SENT RFG SOURCE OVER THE NET. USING THEIR PROGRAM, WE WERE ABLE
  TO RECREATE THE CUSTOMER OBSERVED PROBLEM. IT APPEARS THAT
  THERE IS A LOOP IN THE RFG CODE. IT WAS OBSERVED THAT WHEN
  RUNNING, THE RFG PROGRAM, THE % CPU WENT TO 90%+ FOR A PERIOD
  OF TIME. THIS GIVES ME THE IMPRESSION THAT A TIGHT LOOP IS
  BEING ENTERED IN THE RFG CODE. NO OTHER DOCUMENTATION IS
  REQUIRED OTHER THAN THE RFG SOURCE, WHICH WE ALREADY HAVE.
