High message threshold
A threshold above which the messaging system will take action to limit the addition of more messages to this message point.
A publication point stores a single copy of each message currently queued to a subscription on this publication point. Multiple subscriptions that are queueing the same message will result in a single copy of the message on the publication point. A publication point can reach its high message threshold because a single subscription has many messages queued to it or because many subscriptions have a few, different messages queued to them. If the high message threshold is reached, investigate the state of the individual subscriptions on this publication point to identify the cause.
