Recovery fails if the machine where rabbitmq is running gets rebooted about lyra

[jhalterman]

So just to be clear, you're rebooting the machine or just the restarting rmq (rabbitmqctl stop or stop_app)? If rebooting, how is rmq started again when the machine comes back up?

yes. I am rebooting the machine and restarting rabbitmq manually from command line. I notice that it fails recovery because of "No Route to Host" exception and adding NoRouteToHostException.class in RECURRING_EXCEPTIONS in Config.java solve the problem

[jhalterman]

I can't explain why your setup is throwing NoRouteToHostException after a rmq restart - perhaps the folks on the rabbitmq mailing list could offer some insight, but generally NoRouteToHostException is not a recoverable error which is why Lyra fails. If it is recoverable in your case, as it seems to be, you can simply add this as a recoverable exception via:

config.getRecoverableExceptions().add(NoRouteToHostException.class);

No code changes required :)

thank you 👍

NoRouteToHostException is routing or hostname resolution exception. RabbitMQ cannot affect either in any way.
