Yes, this is most likely a reincarnation error: the time to detect a crash (in FD) and exclude the crashed member is 46.5 seconds, so when you kill and restart a node within ~ 46 secs, that node will get the same port and be reincarnated. Workarounds (besides using 2.8): - Add FD_SOCK as described on then JGroups wiki - Don't se bind_port in TCP Bela View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4228910#...
