Perhaps persistence isn't needed for those messages at all. 30 seconds is bordering on too fast to restart a broker in many cases.
With that said, it sounds like there may be at least one bug here. If a junit case can be written to prove this case, that would help a lot. Alternatively, a minimal client that demonstrates the problem would help.
