[jboss-jira] [JBoss JIRA] Commented: (JBMESSAGING-1691) JBM2 cluster fails under heavy load

[Tim Fox (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBMESSAGING-1691?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12478530#action_12478530 ] 

Tim Fox commented on JBMESSAGING-1691:
--------------------------------------

A couple of questions:

1) Why do you have the live and backup on the same node? If that node crashes the backup will crash too and will be useless

2) Does the problem occur if you run the tests *outside* eclipse? I don't recommend running test clients in eclipse - if you set breakpoints then that will cause pings not to be sent and the system will fail over.

>          Issue Type: Bug
>          Components: JMS Clustering
>    Affects Versions: 2.0.0.beta4
>         Environment: Linux-debian 64bits 8G RAM - Java1.6 update14

> I have a cluster of 2 nodes; A and B:
> In nodeA, I have JMB2-NodeA-live and JBM2-NodeB-backup.
> In nodeB, I have JMB2-NodeB-live and JBM2-NodeA-backup.
> I have a client running in NodeA (eclipseProject "Jbm2ClusterTest-NodeA.zip") and an other client running in NodeB (eclipseProject "Jbm2ClusterTest-NodeB.zip") - Both client starts on the same time.
> In each project there's a Junit testcase (TestLauncher.testTenantPool) to start the test.
> I also attached the configuration (config/stand-alone/clustered) for each node (Live/Backup).
> BTW; I tried with the trunk build (07-23-2009) and JBM2-Beta3.
> I faced the following issues:
> Connection failure after producing 600k and consuming 400K messages of the InboundQueue in each node.
> If the failover kick off then after few min both BackUp and Live servers will be listening to the cluster which leads to "more than one broadcasters on the network broadcasting the same node id".
> I also see "failed to accept connection: too many open files".
> Let me know if you have any question,
> Abdel
