我們的 GKE 集群開始顯示連通性代理錯誤:
connection read failure" err="read tcp 172.16.51.22:49332->172.16.51.8:10250: use of closed network connection" connectionID=1
和
conn write failure" err="write tcp 172.16.51.22:49332->172.16.51.8:10250: use of closed network connection" connectionID=1
和
could not read stream" err="rpc error: code = Unavailable desc = closing transport due to: connection error: desc = \"error reading from server: EOF\", received prior goaway: code: ENHANCE_YOUR_CALM, debug data: \"too_many_pings\
這些錯誤每 5 分鐘出現一次,有時不會顯示最後一個錯誤。
我們嘗試將 GKE 叢集更新到版本 1.22.6-gke.300,但沒有幫助。
那麼問題是我們要如何擺脫這個錯誤呢?或可能是什麼原因導致錯誤?
