Hi, If you enable DLQ to non-persistent message (it's disabled by default), then, IMHO, any message stored in DLQ should survive to broker restart (else it's not really a DLQ). Again, as non-persistent messages are not supposed to go in DLQ. To send the non-persistent messages to DLQ, you have to use for instance:
<sharedDeadLetterStrategy processNonPersistent="true" /> In that case, it makes sense to "store" the message persistently in the DLQ.
