Are there any messages in the application logs? Messages from camel indicating failures on messages (aka exchanges)?
Messages from ActiveMQ (or camel's JMS component) indicating lost connection and need to reconnect? Connection pooling and consumer caching may be coming into play. Although if there is only one message lost each time, with a large number of successful messages in between, then consumer caching probably isn't involved. Note that the connection setup for camel is very important. -- View this message in context: http://activemq.2283324.n4.nabble.com/Help-with-a-Failover-testing-that-shows-missing-messages-tp4707916p4708424.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
