-The optional 'replyToTimeout' (defined in milliseconds) is used to determine how long a dynamic reply-to destination should be monitored for validation purposes.

Therefore the configuration can identify such situations, and monitor the reply-to destination for the response. However, if a response is not delivered in a particular time period, we need to be able to discontinue the validation of the dynamic endpoint. If this did not occur, then over time too many endpoints would be monitored, which may result in out-of-memory problems. The default timeout period is 10 seconds.
