[LTS] LVQ + non-destructive not deliverying message to existing consumer

XMLWordPrintable

    • +
    • Previously, if a client acknowledged a message on a non-destructive last value queue, and that message was subsequently replaced by another last value, the broker did not deliver the message to the client. This issue is resolved.

      When a client acknowledges a message on a non-destructive LVQ and that message is subsequently replaced by another "last value" the broker does not deliver this message to the client.
