The Cosmos-SDK gRPC server never sets MaxConcurrentStreams, and a fork already fixed it
Cosmos-SDK builds its gRPC server without grpc.MaxConcurrentStreams, so grpc-go defaults to an effectively unbounded stream count and advertises no cap to clients: each held stream pins roughly 7 KB of server state, reaching 7.6 GB RSS at the top of the tested sweep with no plateau in sight.
