No ideas? As a work-around I'm now thinking about running a scheduled task that restarts the MessageListener every hour. That's a work-around that shouldn't really be necessary, right? A colleague told me yesterday that he did exactly that in a personal project of his. So, I'm probably not the only one with this problem, although I couldn't find anything related to that on the net.
