>             Project: ActiveMQ

> Creating an unrestricted or selector constrained QueueBrowser does not return messages that are in the persistent store but not paged into memory.
> (i.e. only members of org.apache.activemq.broker.region.Queue.pagedInMessages can ultimately be queried) 
> Once the memory usage limit for a queue is reached no further messages can be paged in and this renders the remaining messages in KahaDB files opaque to QueueBrowser instances.
> Alternatively is there a KahaDB specific tool for querying messages in the log files directly?
