Subject [jira] Created: (AMQNET-294) durable subscription message loss when master broker fails to slave

durable subscription message loss when master broker fails to slave
-------------------------------------------------------------------

                 Key: AMQNET-294
                 URL: https://issues.apache.org/activemq/browse/AMQNET-294
             Project: ActiveMQ .Net
          Issue Type: Bug
          Components: NMS
    Affects Versions: 1.4.1
         Environment: Windows 7 (client), Windows Server 2008 64-bit (server brokers run on),
Sql Server 2008 (database)
            Reporter: Mark Gellings
            Assignee: Jim Gomes
             Fix For: 1.5.0
         Attachments: Apache.NMS.Test.zip

We are seeing message loss on a durable subscription when using NMS ActiveMQ v1.4.1 and ActiveMQ
v5.4.1.

Please run the included NUnit test and watch the console output.  When it says "Failover the
broker now!" do as it says.  About 75% of the time less than half of the expected 250 messages
come through.

Using version 1.1 of NMS the majority of the time the test passes.  I have seen it fail only
a few times with this earlier version, and when it does there are only a couple messages that
don't come through.

In the zip file will be the unit test, and a config directory containing the master and slave
activemq configurations.  We are using JDBC master/slave.
