>  I find a strange critical bug using QueueBrowser in an application and same issue using
HermesJMS.
> 2 brokers in a network broker configured with static uri
> Starting with clean oracle DB ACTIVEMQ_MSGS for broker 1 and broker 2
> 1) I send 10 messages in queue A on broker 1
> 2) checking the broker 1 DB, I find 10 rows and 0 rows on broker 2 DB -> OK
> 3) I try to browse a first time the queue A on broker2 that return an empty list ->
OK
> 4) I try to browse 5 times the queue A on broker2 that finally return my 10 messages
-> KO
> 5) cheking the broker 1 DB, still 10 rows and 41 rows on broker 2 DB -> KO
> 6) I consume messages from broker 2 that return 10 messages
> 7) checking the broker 1 DB return 0 rows and still 41 rows on DB broker 2 -> KO
> 8) I restart the broker 2
> 9) I try to consume messages from broker 2 and I receive again my 10 messages -> critical
!!!!
> 10 ) I restart again the broker 2 and I can consume again 10 messages, etc... until broker2
DB is empty.
> I try to add dynamicOnly="true" and/or conduitSubscriptions="false" but I have always
the same problem.
