Hi If you use dynamic request and response queues (eg use many queues instead of few) and if those queues are not to be reused, then you would need to close the resources when you are done.
So it would only make sense to reuse the producer template for queues you want to reuse in the future. And for one time usage only, then create a new template, and stop it after use. Also Camel 2.10.x is a bit old, you may try upgrading as we fix stuff in newer releases.
