    Shutdown cluster node: Timing problem?

      Hi folks,

       

      I'm using JBoss 5.1.0 EAP and I've set up a cluster with 2 nodes.

       

      From time to time, when I shutdown one node (B with ip-address XXX), the other node (A, with ip-address YYY) logs this messages:

      2010-11-11 11:14:08,565 ERROR [org.jgroups.blocks.ConnectionTable] failed sending data to XXX:7900: java.net.SocketException: Socket closed

      server.log from node B (the one, that is shutting down):

      2010-11-11 11:14:08,669 ERROR [org.jgroups.blocks.ConnectionTable] failed sending data to YYY:7900: java.net.SocketException: Socket closed
2010-11-11 11:14:10,669 ERROR [org.jgroups.protocols.UNICAST] XXX:55200: sender window for YYY:55066 not found

       

      After restarting node B the two nodes build a cluster again without any error or warning messages.

      I am wondering if these errors are just a timing problem or if there is a really problem I should carry about.

       

      I would appreciate any hints.

       

      Thanks in advance,

      Kevin
