[jboss-jira] [JBoss JIRA] (WFLY-6781) Wildfly cluster's failover functionality doesn't work as expected

[Miroslav Novak (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-6781?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13260098#comment-13260098 ] 

Miroslav Novak commented on WFLY-6781:
--------------------------------------

I don't see any kind of interesting failure or error. Not sure where the problem might be as I'm not sure what SL.war is actually doing. How it's reading messages from queue? I guess it's using {{RemoteConnectionFactory}} to do that so it most likely does not use MDB (message driven beans).

What is interesting is that {{<connection-ttl>-1</connection-ttl>}} in configuration of {{RemoteConnectionFactory}}. Could you set it to 60000ms and try again? With -1 dead connections never timeout.

> Following are the testing scenarios we did and the outcome:-
> 1. Network disabling on a VM for testing failover – Not working for both Linux and Windows environment.
> 2. Power off of a VM using VMware client  for testing failover – Is working on Linux environment but not working on windows environment.
> 3. Ctrl + C method to stop services on a node for testing failover – works on both linux and windows environment
> 4. Stopping server running on Node /VM using Admin Console  for testing failover  - works on both linux and windows environment.
> Jgroups subsystem configuration in domain.xml we have is below:-
