ok for FD. However is FC appropriate for REPL_ASYNC (the doc suggests it's not ideal) ? I think the #1 priority is to detect failure accurately - I am just wondering what options are left after adding FD if the problem persists. Last question: is upgrading jgroups to 2.4 (instead of whatever was shipped with 1.4.0SP1) safe? is it recommended? PS: it would be awesome if you could add the version to the jars names in the JC distribution :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3990441#...
