I could not find any answer here in the forums or in the documentation. I need to understand what JBoss 3.2.3 will do if I have an HASingleton running on Node A in a cluster of Node A and Node B, then suddenly someone pulls out the network cable from the switch. Assume both that the OS will shut down its TCP stack and not, i.e. JBoss can either see the network is down or not. Will the HASingleton now be started on both nodes?
I just want to add a question - what is the expected behaviour in various other conditions such as if the JVM crashes on Node A (thus instant death - no time for JBoss to send notifications). Is the HASingleton supposed to start up on Node B? Because it doesn't...
