hi, we have a App server cluster whose nodes are on different VLANs. It has been observed that JBOSS cache doesnt synchronise across these nodes. In effect all the nodes are running on local cache although the cache mode has been set to REPL_SYNC. We are currently using UDP. Any ideas to how to get the cache working in REPL_SYNC mode in this scenario? Any help is greatly appreciated. Thanks Raghu View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4040497#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
