[jira] [Created] (AMQ-3376) Master/slave + cluster leaves messages
on slave
Master/slave + cluster leaves messages on slave
-----------------------------------------------
Key: AMQ-3376
URL: https://issues.apache.org/jira/browse/AMQ-3376
Project: ActiveMQ
Issue Type: Bug
Components: Broker, Message Store
Affects Versions: 5.5.0
Environment: OS: Gentoo Linux.
AMQ: apache-activemq-5.5.0-bin.tar.gz downloaded from http://activemq.apache.org/
Reporter: Eivind Sivertsen
I've setup 4 servers: two master/slave pairs, where the masters are clustered. Topology looks like this:
!http://activemq.2283324.n4.nabble.com/file/n3617053/amq_setup.001.jpg!
All nodes run on the same host, but within separate folders on the filesystem, so no nodes are sharing anything.
I set up consumers on Node 1 and Node 3.
I start producing messages to Node 1.
Messages are distributed (load balanced) across Node 1 and Node 3 as expected, so consumers on both nodes receive messages.
Messages produced to Node 1 are written to the slave node, Node 2, as expected. But messages that are forwarded to Node 3 for consumption there, are not deleted from Node 2.
If I produce 1000 messages to Node 1, and 400 of those are forwarded to Node 3, there are 400 messages left on Node 2 when all messages are consumed from Node 1 and Node 3 (queueSize = 0 on both). So the messages that are consumed on Node 1 are deleted from Node 2, but not those forwarded to Node 3.
A possible fix: messages that are received on a master node, but forwarded to another node in the cluster, are *not* stored on the slave node.
The [ActiveMQ User mail list discussion|http://activemq.2283324.n4.nabble.com/Master-slave-cluster-leaves-messages-on-slave-td3617053.html] has links to the configurations for node 1-4.
