I got the logs and it shows me that Jboss is continuously trying to connect to the host that just got rebooted or crashed. I thought when EJB is @clustered it will round robin the invocation and not try same host over and over again. But what I am seeing is that Jboss repeatedly tries to connecto failed host. Could someone tell me what's going on? --- 2008-12-31 12:20:14,287 DEBUG [transport.socket.MicroSocketClientInvoker:ajp-0.0.0.0-8009-99] - SocketClientInvoker[18b118, socket://10.10.8.77:3873] got Exception java.net.NoRouteToHostException: No route to host, creation attempt took 3001 ms 2008-12-31 12:20:14,287 DEBUG [transport.socket.MicroSocketClientInvoker:ajp-0.0.0.0-8009-86] - SocketClientInvoker[18b118, socket://10.10.8.77:3873] got Exception java.net.NoRouteToHostException: No route to host, creation attempt took 3001 ms 2008-12-31 12:20:17,291 DEBUG [transport.socket.MicroSocketClientInvoker:ajp-0.0.0.0-8009-86] - SocketClientInvoker[18b118, socket://10.10.8.77:3873] got Exception java.net.NoRouteToHostException: No route to host, creation attempt took 3001 ms 2008-12-31 12:20:17,292 DEBUG [transport.socket.MicroSocketClientInvoker:ajp-0.0.0.0-8009-99] - SocketClientInvoker[18b118, socket://10.10.8.77:3873] got Exception java.net.NoRouteToHostException: No route to host, creation attempt took 3002 ms ..........
