That's fine if there's still some other nodes in the cluster. Let's say we've got a cluster of A,B and A has just picked the coordinator role and it's pushing the state. If A is stopped in the middle of that, it does not matter that the persistent state is not complete because B will assume coordinator next and would push the in-memory state to the cache loader. Problem solved. However, if the same happens now happens with B which is the last node, then the persistent state will remain corrupt. The other potential issue comes from a cluster restart and the coordinator node retrieving the state from a cache loader to which the transfer was not completed successfully. I'm just trying to think of potential problems. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3961810#...
