Subject Re: How to discard messages for the non-durable queue
Date Wed, 25 Mar 2009 12:51:28 GMT
Hi there

have you considered to set a time to live on your messages.
If you send messages NON_PERSISTENT that should work.
If you send PERSISTENT messages, you should probably configure the  
DiscardingDLQBrokerPlugin as well.


Best regards
Andreas
