The "localhost" resolves to a valid domain, and all of the nodes (five of them) run on a single box. We are using JGroups 2.4.1. Is the configuration Okay otherwise? Why does the split happen at all even if all the nodes are running on the same box in the first place? Could it be because of long GC pauses? Could there be any other reasons? Please let us know. Thanks. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4085984#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
