A method of routing messages may include providing a listener registry of a plurality of listeners and associated namespaces so that at least one namespace is associated with each of the plurality of listeners. A message may be received from an originating application, and the message may include a message namespace. The message may be stored in a message queue, and a determination may be made to determine if a listener from the listener registry is associated with the message namespace. If no listener from the listener registry is associated with the message namespace, the message may be stored in a parked message queue separate from the message queue. After the message has been in the parked message queue for a predetermined period of time, the message may be deleted from the parked message queue.
