 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.
