I tried working with the cleanupInterval (the default is 30 secs, not 30 mins as I had indicated below)...
Not sure how to test....I sent a bunch of messages through, and then waited 5 minutes before shutting down the broker and restarting....I still see 2 messages sitting in the pending state in the webconsole (but none of the consumers try to consume these).... So, I'm thinking it's not to do with cleanupInterval? Although a little more explanation on 'cleanupInterval' would be appreciated (as well as most of the other params that are pretty lightly documented)....
