messages not being sent consistently

[Glennstar]

Hi,
I have a test server with the latest 0.2.6 build of poco::mq. It
dispatches messages when there is a process connected to the relevant
queue but not when there are messages on the queue and a process
subsequently connects.
I have added a log below. Any feedback welcome.

Having tested a little bit further it appears that while the messages
are in the front-store, everything is fine. As soon as they are
somitted to the backing store things go wrong. I am running this from
mq.pl. Is there any way I can easily change the backing store engine
to test if this is the case or not?
