I'm running a cluster on JBoss 3.2.5 and am having issues with my instances joining. It seems to only happen when starting up a 3rd or 4th instance to join the cluster. For example, say I have instance A and B running already, and go to start instance C:
1. serverA will acknowledge serverC as a member and update its cluster view properly 2. serverB will spit out the following warning: 2004-08-26 16:52:38,999 WARN [org.jgroups.protocols.pbcast.NAKACK] [serverC:32794 (additional data: 17 bytes)] discarded message from non-member serverC:32799 (additional data: 17 bytes) 3. serverC will hang at this point Why does serverB think serverC is a non-member, when serverA is cool with serverC? And when serverB and serverA are in the same cluster...makes me thing that it's not a config issue. Is there any way to hardcode who your members are to avoid this issue? I found that the issue doesn't happen when using TCP rather than multicast, but it is way too slow in comparison (just clicking around as a single user on my site I saw the page load times go up 3 seconds or so). Any help/suggestions would be greatly appreciated.
