> There is a race between a client join discovery event on server nodes and the moment when a client starts to establish outgoing communication connections. It would cause to rejecting communication connections on server nodes (for example. on requesting data from caches).
> The issue happens on really big topologies (> 300 nodes) or when many clients join simultaneously.
