DeadLetterService in JBoss ESB never consumes messages in DLQ

Solution Unverified - Updated -

Issue

  • I observe that when an exception occurs while an ESB service with the JMS listener is processing a message, the message is finally sent to the DLQ after retries exceed the dLQMaxResent specified in jboss-esb.xml.
  • What I see then, however, is that messages in the DLQ simply increase and the dead letter service in the ESB never consumes them.
  • I guess the dead letter service isn't working properly?
