[jboss-jira] [JBoss JIRA] Commented: (JBAS-6807) Unable to form a cluster Branch_5_x (flush by coordinator at xyz failed)

[Bela Ban (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBAS-6807?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12463484#action_12463484 ] 

Bela Ban commented on JBAS-6807:
--------------------------------

Could you capture a bit of that traffic ? Use wireshark if possible, then we can look at the JGroups messages (with Richard's JGroups module).

Also, you probably need to run this with some cats enabled at TRACE, e.g. org.jgroups.protocols.pbcast.FLUSH, but I'll let Vladimir comment on that. He can then take a better look.

I assume this issue is reproduceable ?
