Timothy Bish closed AMQ-6258.
-----------------------------
    Resolution: Duplicate

This is working as designed.  You can alter the maxBrowsePageSize to allow for more paged in messages but there will be limits due to memory usage that must be considered.

> 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?
