Constant UDP error messgae when running 4.0.4 GA Patch1 with

[romanchr]

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

i think your machine needs a network thats why. multicasting is not possible without a network. create a virtual network the try

Hi,

Thanks for your reply. I tried to figure out how to configure a virtual network but failed. Instead I am using a none clustered version now as the exception is just too annoying.

I still be happy if anyone outhere could point out a bit more detailed instructions.

Thanks & Regards

I'm having the same problem (intermitently) except that I need to leave clustering on! Anyone any further insight?
