Subject Re: Should Total Message Count decrease?
Date Wed, 30 Nov 2011 10:14:28 GMT

first thing: does it occur while there is a consumer? Or only if there
is no consumer? Are you using queues or topics (maybe even with
persistent subscriptions)?

TTL basically works the way you expected, BUT it depends if the
messages are persistent or not, and if you have configured expired
messages to be stored in a dead-letter-queue.

Best regards,
