[jboss-user] [Clustering/JBoss] - discarded message from non-member

[bmelloni]

As far as I can tell I setup a cluster following all the instructions.  But as I start the 2nd server, even without any of my apps deployed, I get the error "discarded message from non-member" several times on the first server.  Needless to say... things get worse when I try to deploy a simple webapp through the farm folder.  I then see lots of errors and although I see the file -slowly (horrendously slowly)- arriving at the other server, the cluster is unusable.  The documentation and troubleshooting FAQs haven't helped.

Does anyone have any clues about the possible causes?

Configuration for both boxes:
- JDK 1.6
- jBoss EAP 4.3
- Windows XP
- Firewall disabled for test
- Run all the jgroups standalone troubleshooting test successfully (problem only when using full jBoss)
- Using the 'all' configuration
- Reduced the network to a linksys router and 2 boxes

Symptoms:

- jGroups seems to start correctly and recognize both boxes:
15:50:45,995 INFO  [DefaultPartition] I am (127.0.0.1:1099) received membershipChanged event:
15:50:45,995 INFO  [DefaultPartition] Dead members: 0 ([])
15:50:45,995 INFO  [DefaultPartition] New Members : 0 ([])
15:50:45,995 INFO  [DefaultPartition] All Members : 2 ([127.0.0.1:1099, 127.0.0.1:1099])
15:51:07,386 INFO  [TreeCache] viewAccepted(): [192.168.11.103:2591|1] [192.168.11.103:2591, 192.168.11.102:1136]
15:51:09,730 INFO  [TreeCache] viewAccepted(): [192.168.11.103:2595|1] [192.168.11.103:2595, 192.168.11.102:1141]

- Then the first server complains about 9 times like:
15:51:24,808 WARN  [NAKACK] 192.168.11.103:2600] discarded message from non-member 192.168.11.102:1147, my view is [192.168.11.1
03:2600|0] [192.168.11.103:2600]

My guess is that I missed configuring something.  Because of the jGroups tests I am reasonably confident that multicast works OK.

I searched this forum (no results), then googled and found lots of similar posts, but no answers.  Any help will be greatly welcome.
