Here is how completion queue shutdown works: Once you call cq->shutdown on a completion queue, you can no longer queue any more events on that queue. One caveat: if you use grpc::ServerContext::AsyncNotifyWhenDone() to register a tag for call cancellation, these will not be returned by cq_->Next() if the server shuts down before the initial request is received for that call.
