Error description

  • If SYSTEM.BROKER.AGGR.TIMEOUT queue has any message then reply
    messages of an aggregation can incorrectly get moved to
    SYSTEM.BROKER.AGGR.UNKNOWN queue. So even if all the reply
    messages arrived, the AggregateReply node completes the
    aggregation only after the timeout/unknown timeout value
    expires.
    

Local fix

    PROBLEM DESCRIPTION:
    If SYSTEM.BROKER.AGGR.TIMEOUT queue has a message then reply
    messages of an aggregation may incorrectly get moved to
    SYSTEM.BROKER.AGGR.UNKNOWN queue if the aggregation fan-in
    message flow is configured with additional instances. Once a
    reply message is moved to SYSTEM.BROKER.AGGR.UNKNOWN queue, even
    if all the reply messages arrives, the AggregateReply node
    completes the aggregation only after the timeout/unknown timeout
    value configured in the node expires.
