> In cluster braindump (when a new member is being added to a cluster) the
> QueuePolicy is not being serialized out as part of the brain dump. As a
> result the newbie cluster can get a mistaken idea of the queue size (in
> bytes).
> After many dequeues, the size can go negative, but since the queue size is an
> unsigned number it wraps around and look like a large positive. Which sets
> off the flow-to-disk code, because it thinks that the queue has gotten too
> large.
> The result: what(): framing-error: Unexpected command start frame.
> (qpid/SessionState.cpp:57)
> This fix just adds a little serialization of the QueuePolicy on to the end of
> the serialization of the Queue.
