    Constant UDP error messgae when running 4.0.4 GA Patch1 with

    romanchr Newbie

      Hi all,

      I am running JBoss 4.0.4GA Patch1 with EJB3 clustering enabled configuration. OS is Windows XP Pro, SP2 and Java version is 1.5.0_06.

      Everything seems to run fine except that I get constant error message somehow related to communication going on.
      Here is the stacktrace:

      08:46:53,363 ERROR [UDP] exception=java.io.OptionalDataException
      at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1253)
      at java.io.ObjectInputStream.readObject(ObjectInputStream.java:339)
      at org.jgroups.util.List.readExternal(List.java:304)
      at org.jgroups.protocols.UDP.handleIncomingUdpPacket(UDP.java:673)
      at org.jgroups.protocols.UDP$IncomingPacketHandler.run(UDP.java:1332)
      at java.lang.Thread.run(Thread.java:595)

      Has anyone seen this before? The exception happens around every 20 sec therefore I assume it could be some JBoss internal polling. I very much doubt that any other software is causing this as JBoss is running on configuration ports-02. And the exception neither related to the port change, as I got it also when running with default configuration.

      Any help appreciated!

      Regards
