Subject ActiveMQ Config to purge 'persistent' messages in DLQ.
Date Fri, 08 Sep 2017 17:28:51 GMT
Hi everyone!

I am having an issue where a subscriber is not running and messages get sent
to the DLQ. The messages are marked 'Persistent'. Is there a way I can make
the DLQ 'persistent' messages to get deleted after a 24h period?

I don't care about redelivery or any kind of checking at this point.

Here is the current config I have:
