Hi all, Puzzled by some behaviour we're seeing on a broker cluster of 3 live Artemis v2.16.0 brokers hosted on k8s which has an F5 in front of it terminating TLS and routing to a k8s node port forwarding to an AMQP acceptor for each broker. The cluster is healthy and has been up for about 2 months without interruption. Each broker has its own storage. The address routing is set up with redistribution delay = 0 and the clustering is using all default settings and static discovery.
Clients all use *non-shared* durable topic subscriptions via QPID JMS v1.0. What we're seeing is that if two separate physical clients attempt to open a connection using the same client ID, Artemis *occasionally* allows both to succeed and allows both to consume the durable subs on 2 different brokers. I thought this was only possible if round-robin routing was explicitly enabled on the clustering configuration by configuring STRICT message load balancing instead of the default ON_DEMAND. Of course, due to the F5, it will appear to Artemis that both clients are running on the same physical host. Is there some "belt and braces" way to prevent 2 connections with one client id in addition to the message load balancing configuration? Thanks, Dave
