Jörn Kottmann commented on UIMA-1658:
-------------------------------------
It seems that the same happens when the network connection to the broker is
lost for a short period of time e.g. through network maintenance. In this case
the services should just try to reconnect until the broker can be reached again.
> UIMA AS worker does not respond to client initialize after failover

> Key: UIMA-1658
> URL: https://issues.apache.org/jira/browse/UIMA-1658
> Project: UIMA
> Issue Type: Bug
> Components: Async Scaleout
> Affects Versions: 2.3AS
> Environment: Ubuntu 8.10 Server, Java 1.6 and ActiveMQ 5.3.0
> Reporter: Jörn Kottmann
>
> A Pure Master Slave Broker is used to increase availability of the broker.
> More information about it can be found in the activemq documentation:
> http://activemq.apache.org/pure-master-slave.html
> In a test we simulated Master failure through killing the process with kill
> -9.
> Here is the log output from the worker node:
> INFO FailoverTransport - Successfully connected to
> tcp://XXX1:61616
> Here I stopped the master broker process with kill -9
> WARN FailoverTransport - Transport failed to tcp://XXX1:61616 ,
> attempting to automatically reconnect due to: java.io.EOFException
> WARN FailoverTransport - Transport failed to tcp://XXX1:61616 ,
> attempting to automatically reconnect due to: java.io.EOFException
> WARN FailoverTransport - Transport failed to tcp://XXX1:61616 ,
> attempting to automatically reconnect due to: java.io.EOFException
> INFO FailoverTransport - Successfully reconnected to
> tcp://XXX2:61616
> INFO FailoverTransport - Successfully reconnected to
> tcp://XXX2:61616
> INFO FailoverTransport - Successfully reconnected to
> tcp://XXX2:61616
> Afterwards the client was restarted but got a time out error during
> initialize.
> During initializes it sends a message to the worker nodes input queue, but
> this
> message if never retrieved.
> I used the activemq web interface to get some information about the message:
> Command 2001
> MessageFrom ID:XXXX-51032-1257865414664-0:1:1
> ServerURI failover:(tcp://XXX1:61616,tcp://XXX2:61616)?randomize=false
> MessageType 3000
