> durable subscription message loss when master broker fails to slave
> -------------------------------------------------------------------
>
> Key: AMQNET-294
> URL: https://issues.apache.org/jira/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 (2).zip, Apache.NMS.Test.zip,
> DurableConsumerTest.cs, DurableSubscriberFailoverTest.java, NMSLog.txt,
> TimsTestRevisedSlightly.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.
