Looks like we have a temporarily issue with our network, and our Akka app restarted but failed to initialize the cluster/classic remotting codes, and it remains as a stale process, we have to manually restart the process.
According to the exception stack and the codes, I think the app timeouts when trying to bind the host and port, this is fine and the log is clear. But how could I catch this exception and shutdown the Akka app in a coordinate way?
BTW, we don’t have any resource allocated before the Akka actor system is fully functional.
