Hi all,
I have been allocated an issue to resolve on JBoss clustering. I'd like to understand what is supposed to happen before I dive into our application issues.
My testing environment.
-----------------------------
Machine (a) WinXP
Virtual Machine (b) VMWare Instance running RedHat 4 (on same machine)
I have successfully managed to get the two JBoss instances clustering after initial startup (no applications installed) and all is happy until I disable the network card in the virtual machine (trying to simulate a network outage).
When I bring it back online they fail to re-establish a cluster, with
"[FD] I was suspected by 192.168.56.130:1123; ignoring the SUSPECT message and sending back a HEARTBEAT_ACK" messages until I restart either of the JBoss instances.
If anyone could shed some light on why this happens, I'd be grateful.
thank you Mogy ...
