[rabbitmq-discuss] OOM kill

[Dmitry Andrianov]

Oh, it is the bit I keep forgetting about - the fact you want to continue accepting connections to let consumers in.

But that means that is possible to DOS any internet facing Rabbit...

Are there any mechanisms in RabbitMQ to listen on two ports or network addresses at the same time while being able to set independent connection limits on these?
It would allow to limit number of clients coming from Internet while still be able to accept consumers from trusted servers.

Cheers
