Assertion Error in the AMQ Broker in a pure "Master/Slave" scenario...
----------------------------------------------------------------------
Key: AMQ-1336
URL: https://issues.apache.org/activemq/browse/AMQ-1336
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 4.1.1
Environment: Windows
Reporter: Ashwin Karpe
Attachments: Exercise3_Failover.zip, exercise_setup.bat
I am using version 4.1.2.4.
When I start the master and slave Broker everything starts correctly. No errors
etc.
When I start the consumer, no issues there either...
However when I start the producer on every invocation, I find the following
error popping up on the master brokers console...
10:08:39 ERROR Slave Failed

The funny thing is that I cannot explain why this happens, everything behaves
correctly i.e the fail-over does happen when the master dies.
Please use the attachment to re-create the issue. Not sure what this wierd
problem is...
