- Apiserver add a new flag --goaway-chance which is the fraction of requests that will be closed gracefully(GOAWAY) to prevent HTTP/2 clients from getting stuck on a single apiserver. 
  After the connection closed(received GOAWAY), the client's other in-flight requests won't be affected, and the client will reconnect. 

- Clients required to use go1.15.8+ or go1.16+ if kube-apiserver has the goaway feature enabled to avoid unexpected data race condition. ([#98809](https://github.com/kubernetes/kubernetes/pull/98809), [@answer1991](https://github.com/answer1991))
