Subject [jira] Commented: (AMQNET-294) durable subscription message loss when master broker fails to slave
Date Wed, 29 Dec 2010 14:31:45 GMT

    [ https://issues.apache.org/jira/browse/AMQNET-294?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12975783#action_12975783
] 

Timothy Bish commented on AMQNET-294:
-------------------------------------

This appears to be a problem with the broker recovering the subscription.  Opened AMQ-3106
to track the problem.

> 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.
