Subject [jira] [Updated] (AMQ-3413) Broker losing messages in a NoB while disconnected
Date Fri, 22 Jul 2011 16:49:58 GMT

     [ https://issues.apache.org/jira/browse/AMQ-3413?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andreas Calvo updated AMQ-3413:
-------------------------------

    Description: 
When a broker gets disconnected from the network (I.E. power down network infrastructure)
messages sent during this period are lost.

Example:
Client 1 < - >  Broker A < - > Broker B < - > Broker C < - > Client
2

Client 1 and 2 create a producer to send message to a Topic.
Client 1 and 2 create a durable subscriber to the Topic.

If Broker A gets disconnected (unplugged from the network), during the first maxInactivityDuration
ms messages are lost. Once it detects the dead broker, those messages are not lost, meaning
that when Broker A reconnects to the network it gets starting from those messages.
