Inconsistency between queue length and queue browsing

Hello, I'm facing an inconsistency in the behaviour of ActiveMQ for which I cannot find an easy explanation. The facts: $ ./activemq-admin query -QQueue=provRequests1 DequeueCount = 0 Name = provRequests1 MinEnqueueTime = 259749107 CursorMemoryUsage = 2905853 MaxAuditDepth = 2048 Destination

Serious dispatch issue

I already put this in a comment on https://issues.apache.org/activemq/browse/AMQ-2009 which might explain why people experience this issue. I have a simple cause which can cause dispatch problem: 1. setup a network of broker1, broker2, bridged by multicast discovery 2. make a producer send 5 msg
