Description

I have found during testing that the reported size of the messages in a KahaDB store can be shown as too high in certain cases. The message count values are accurate, however.

My testing as shown that when publishing a large quantity of messages with several producers (a couple hundred thousand) and then consuming them with several consumers, when all the messages are consumed and the count is 0, the reported size will still be greater than 0.
