[jboss-user] [Clustering/JBoss] - Re: Network Loss in a 1 to n Node Cluster

[jbirkenmaier]

Thanks for the quick reply. Regarding the first problem. I see the view change on node 1 when I Ctrl-C JBoss on node 2. However, I don't see the view change when I unplug the network cable. 

Here is what's logged when I unplug the cable:

10:41:27,090 INFO  [dragoneyes] (UpHandler (STATE_TRANSFER)) Suspected member: 192.168.69.253:33013

Here is what's logged when the cable is plugged back in:

JBoss/JGroups sees the loss and restoration of the network. Is there no way to hook into  UpHandler or AsynchViewChangeHandler to catch the notification? The viewChange method just isn't doing it.
