Hi all, I've been playing with the clustering for a bit now using
JBoss3.0.1RC1. I've got a 2 node cluster with a SFSB that is clustered,
here's something I'm seeing:
1. Node A and B are brought up fine and see each other.
2. I hit my app and see my SFSB message call on A.
3. I kill A, hit my app again and see my SFSB call on B.
4. I bring back up A, B sees it and the both say they have 2 members.
5. I hit my app and see my SFSB message call on B.
6. I kill B, hit my app again and BOOM, A says:
