The behaviour you describe is exactly what should happen - once a message queued for a client session is delivered, it will be removed from the persistence store. If you are referring to retained messages however, the messages will only be removed when the retained message itself is removed - by sending a retained message to the same topic, but with a zero length payload.

I hope that helps.

Regards,

Roger
