IT42402: AGGREGATEREPLY NODE PROPAGATES THE UNRECOGNIZED MESSAGE TO THE UNKNOWN TERMINAL BEFORE THE UNKNOWN MESSAGE TIMEOUT EXPIRY.

APAR status

• Closed as program error.

Error description

• When a message arrives at the In terminal of an AggregateReply
  node, it is examined to see if it is an expected reply message.
  If Unknown Message Timeout property of the AggregateReply node
  is set then, a message that cannot be recognized immediately as
  a valid reply is held persistently in the integration node for
  the number of seconds that you specified as the Unknown Message
  Timeout property. If the unknown timeout interval expires, and
  the message is recognized, it is processed and If it is not
  recognized, the message is propagated to the Unknown terminal.
  But the AggregateReply node currently does not wait till the
  configured Unknown Message Timeout value to process the
  unrecognized messages and it can even cause the unrecognized
  messages to get discarded. For example, if Unknown Message
  Timeout property is set as '60' then it may wait only for 6
  seconds to process the unrecognized message.
  

Local fix

• Specify the  Unknown Message Timeout property value as tenths of
  a second ie for using 6 second as the  Unknown Message Timeout,
  set '60' as the Unknown Message Timeout property value in the
  AggregateReply node.
