Hi! I'm running two servers. Same config each, and same log output from both. The servers are Xen-provisioned VSP in the same data center. I'm thinking this may be an issue with Xen multicast configuration. Can JGroups can be configured to use TCP and a list of IP addresses instead of multicast? Is replication possible in a VPS environment?? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4263798#...
