Hi Neil,

But, shortly after that, I see these messages (This is the output
on controller 1):

2006-11-03 11:22:44,136 WARN  protocols.pbcast.GMS I am the coord and I'm
being am suspected -- will probably leave shortly
2006-11-03 11:22:44,144 WARN  protocols.pbcast.GMS I (206.123.70.59:7800) am

[206.123.70.59:7800, 38.100.86.36:7800])
2006-11-03 11:22:44,389 ERROR continuent.hedera.channel Unhandled JGroups
message type (class org.jgroups.ExitEvent): ExitEvent.
For some reason, JGroups decides that there is a failure in the total order sequencer and decides to quit the group by itself. You might have to tune your failure detectors timeouts (they might be too short). The best would be to get help from the JGroups mailing list (I saw that you already posted there and that's probably the best thing to do).

When I try to issue a command against the database, I see these messages
(on controller 1):

2006-11-03 11:25:22,030 WARN  controller.RequestManager.cbsweb An error
occured while executing distributed request 1
org.continuent.hedera.channel.NotConnectedException: ChannelClosedException

It looks like they are not liking the tunneled connections.

Any ideas how to fix this?
The problem is once JGroups has exited the group, it does not reconnect (or try to re-join). This is an issue since your controller becomes isolated from the rest of the world. The fix is to get a working configuration of JGroups (or try Appia with the help of Nuno).

Keep us posted with your findings,
Emmanuel
