PK94148: LOOP IN IPI4PROC WHEN FLUSHING TRANSACTIONS FOR HIGH WATER MARK (HWM) PROCESSING

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• HWM processing ignores the currently active transaction; we
  don't want to flush our active task. But if the next entry on
  the queue is not a transaction (i.e. Response or Ancilliary
  record) then the originating transaction can be null, which
  causes this record to be ignored, but we do not advance the
  transaction pointers.

  Loop in IPI4PROC when flushing transactions for high water
  mark (HWM) processing.
  HWM processing ignores the currently active transaction;
  we don't want to flush our active task. But if the next
  entry on the queue is not a transaction (i.e. Response
  or Ancilliary record) then the originating transaction
  can be null, which causes this record to be ignored, but
  we do not advance the transaction pointers.
  

Problem conclusion

• If the currently active transaction is encountered in HWM
  processing, ensure that we advance the transaction pointers
  to the next valid transaction record to be flushed.
