Setting compatibility mode worked...I think.

I now get:

My partition is 'TCEPartition'/45566. I can now see entries for 'Tomcat-TCEPartition'/45577 as well.

Is this correct? it is certainly different.

Also, consider this:


  | [root at bob1 bin]# ./probe.sh -addr 230.0.0.88 -port 45566
  | 
  | -- send probe on /230.0.0.88:45566
  | 
  | 
  | 
  | [root at bob1 bin]#
  | 

in my log, I see:


  | 2007-04-11 09:33:00,434 WARN  [org.jgroups.protocols.UDP] packet from 147.209.225.205:42856 has different version (20821) from ours (241). This may cause problems

  | 

Not what I expected...and not what WAS happening

FYI, my probe.sh is:


  | #!/bin/sh

  | fi
  | 
  | $JAVA_HOME/bin/java -Djgroups.marshalling.compatible=true -cp $CP org.jgroups.tests.Probe $*

The actual cluster seems OK...we are just talking about the behaviour of probe.sh (aren't we?).

Cheers,
