Unfortunately, for some reasons, We can not use extra Gossip Route and FILE_PING is not compliant to JGroups 2.2.7 right?...Schade How about the solution of adding attributes, persistent_ports? But it seems, it's also not compliant to version 2.2.7, because ERROR message: can't recognize this attribute. Should upgrade the JGroups version? Then which one? I tried 2.4.5GA, but unstable. I also want that Auto-connection feature is set true by default..So I'll try to use 2.4.2. Is there any recommendation or experience to share? Thanks a lot. ------------------- LarryJ View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4229401#...
