Subject Re: How can I find messages that have been unconsumed for "too long"?
Date Thu, 30 Aug 2007 11:03:26 GMT

That was my first expectation - that they would go to the DLQ but they never
appeared to go there.  Perhaps the bug you mention is the reason.  Having
found this behaviour I went and did some searching - the outcome was that it
sounded like brokers were expected to destroy the expired messages.

I'll have a look at AMQ-1112.  Perhaps it's been fixed and I can get the
latest snapshot and try again.

Thanks,
