Re: [akka-user] Cluster seed nodes resulting in multiple split brains?

Thanks for the information. I have read most of these. Can I take it from your responses that you agree that this could be a split brain problem? I am just wondering if using all nodes as seed nodes is what is causing the issue. In production our seed nodes are fixed IPs. But when we run in the

ConductR* is designed to properly seed, and update, Akka Cluster based applications, and the Akka Split Brain Resolver provides deterministic partition handling. ConductR runs well on EC2: https://conductr.lightbend.com/docs/1.0.x/Install#EC2-Installation * ConductR and SBR are Lightbend

Are you aware of the importance of the first seed node, the one you have listed as first element in sees-nodes list? See documentation. You can get decent behavior if you wait with joining until the list of discovered nodes stabilize, i.e. not changing within X seconds. Then sort them to make

Your contribution makes ID strategy automatic even better, you know automatic = explicit + incremental right? So I think it would also work for your project, but I do understand why you have chosen explicit as you want to fail if you introduce a new class and forget to register it. I use
