Wait, those sound like two separate things. When you say "messages aren't de-queued even though they are acknowledged when our system consumes them", are you saying that the broker isn't removing from the store messages that have been acknowledged by all subscribers (active or offline)? Because that's very different from "We are setting the time to live on the messages but they don't time out."
Let's start with timing out of messages. For a given message, how do you know it wasn't timed out, and how long after its JMSExpiration time did you check? Have you confirmed that the header is actually being set on each message, and that it's being set with the right timestamp value? Have you confirmed whether the settings to remove offline durable subscribers are working as expected? JConsole's MBeans tab can help here. Last, let's come back to what I started with: how do you know that messages that have been acknowledged by all subscribers (not just all active subscribers) are not being "dequeued," and what do you mean by that word in this context? Dequeues on topics are specific to a subscriber, so are you saying that for a particular subscriber they ack a message but the dequeue count for that subscription doesn't increase? And how do you know that all subscribers have acknowledged the message? Also, what does "ActiveMQ jams from storing too much data either in cache or in the db" mean? Producer Flow Control? OOM? Filling the disk your persistent store uses? Performance degradation? Please be more specific about the symptoms of the problem. You say "in the db;" does that mean you're using the JDBC store?
