  ****************************************************************
  Abend S0C4 in IPI4PROC in end of transaction (EOT)
  processing when traversing the transaction chain for
  MODE=MULT transactions.
  

Problem conclusion

• MODE=MULT transactions may result in multiple transactions
  being chained from a single Unit of Recovery (UOR).In EOT
  processing the chain is traversed sequentially to remove
  the completed transaction from the list. The chain is
  intended to be scanned sequentially from the first entry,
  however in some situations the first entry could be skipped,
  in which case the transaction may not be found and an
  invalid pointer left which could result in a subsequent
  abend S0C4, depending on whether the storage addressed by
  the missed pointer was released/reused for different
  entry types.
