This has improved a bit in Camel 2.10 onwards, as Camel will not perform redelivery attempts when shutting down aggressively (eg during <a shape="rect" href="graceful-shutdown.html">Graceful Shutdown</a> and timeout hit). From Camel 2.11 onwards there is a new option <code>allowRedeliveryWhileStopping</code> which you can use to control if redelivery is allowed or not; notice that any in progress redelivery will still be executed. This option can only disallow
any redelivery to be executed <strong>after</strong> the stopping of a route/shutdown of Camel has been triggered. If a redelivery is dissallowed then a <code>RejectedExcutionException</code> is set on the <a shape="rect" href="exchange.html">Exchange</a> and the processing of the <a shape="rect" href="exchange.html">Exchange</a> stops. This means any consumer will see the <a shape="rect" href="exchange.html">Exchange</a> as failed due the <code>RejectedExecutionException</code>.</p><p>The default value is <code>true</code> to be backwards compatible as before.
