Hi,
Maybe your messages in the topic (if I understand correctly) are non persistent
messages.
By default, the non persistent messages are not store in the DLQ: only
persistent messages go into the DLQ.
If you want to consider non persistent messages for DLQ, you have to enable it
with something like (at destination policy level):
<deadLetterStrategy>
<sharedDeadLetterStrategy processNonPersistent="true" />
</deadLetterStrategy>
