UDP warnings in the log file

[gubenc2]

Hi all,

We installed new JBoss servers on our
company network and this caused a problem
both on the new and the old JBoss servers.
The server logs are full of UDP warnings like this:

2004-10-21 13:35:29,865 WARN [org.jgroups.protocols.UDP] packet from /10.1.1.11:45566 has different version (0220) from ours (0224). This may cause problems
2004-10-21 13:35:29,865 WARN [org.jgroups.protocols.UDP] discarded message from different group (). Sender was HERCULES:1085 (additional data: 14 bytes)

We use JBoss in 3.2.5 and 3.2.3 severs with
the all configuration.We think the problem
is related to clustering. We do not use clustering and do not know how to configure it. It seems that the JBoss servers would like to discover each other for clustering. Is our guess right? Could someone please tell us how to turn off clustering?

The all configuration contains many services generally not needed, and if your not using clustering you should not be starting with the all configuration. What is in all that you need?

Dear Scott,

We use the all configuration because we use
havy clients which need RMI access to our beans.
As far as we know the default configuration does
not contain RMI. I tried the default configuration
with a session bean with remote interface and
could not deploy it until I removed the remote
interface. There were no such problem in the
all configuration.

The default config supports rmi using either the sun jrmp protocol or our proprietary socket protocol. If you need rmi with the iiop protocol that can easily be added to the default config by moving over the iiop-service.xml, and its jars and config.
