Description

Max message size violations are enforced with a connection closure. See DISPATCH-975

Consider the case of messages coming to an interior router from a client on an edge router. If the edge router size limit is larger than the interior router size limit and a client sends a message whose size is between the two limits then the interior router closes the connection to the edge router. This is undesirable.

If the edge router, or any router, honored the attach frame max-message-size then the interior router's size limit could be enforced completely by the edge router. The clients message to the interior router would be aborted and the connection would not be taken down.

This same feature could apply to any AMQP peer and not just apply to interrouter connections.
