Thats because you do request/reply over JMS and Camel will by default use a 20 sec timeout waiting for the reply
In the stacktrace you can see the caused exception Caused by: org.apache.camel.ExchangeTimedOutException: The OUT message was not received within: 20000 millis. In your test just raise that timeout value to be higher (its the requestTimeout option) http://camel.apache.org/jms -- View this message in context: http://camel.465427.n5.nabble.com/Concurrent-processing-Problem-of-600-messages-at-the-same-time-tp3258545p3258556.html Sent from the Camel - Users mailing list archive at Nabble.com.
