> I have seen some failures, related to {{ZkController.OnReconnect}} that made
> the node "gone" ( it is not present in "/live_nodes" ). In fact any exception
> during {{OnReconnect.command()}} execution will made the node "gone". Some of
> them are
> - {{ZkController.createEphemeralLiveNode()}} can throw NodeExistsException
> - {{OutOfMemoryError : unable to create new native Thread}} during adding
> core to {{executorService}} for recovering
