Subject Re: QueueBrowsing with MasterSlave Problem
Date Fri, 05 May 2006 18:50:43 GMT

Thank you very much for the fix. It solves the lockup issue, however I now
receive exceptions on the slave broker of the form when browsing a queue:

ERROR ManagedRegionBroker            - Failed to register subscription
QueueBrowserSubscription:
consumer=ID:<masterhostname>-35805-1146854230285-1:2:1:1, destinations=0,
dispatched=0, delivered=0, pending=0
javax.management.InstanceAlreadyExistsException:
