For more efficient message processing to Integration Server, make sure that you validate the listener notification filter criteria when configuring listener notifications so that it does not conflict with the listener filter criteria. For example, if both a listener and its notification filter on the same field but specify different values, the notification filter criteria can never match. In this case, the listener will remove the message off the topic because it passed the listener filter criteria. However, the notification will not be processed because the value of the field will not have a match value for the notification filter criteria.
