[ehsanrocket]

What is the issue?
we use grpc for communicating between tow apps
we use linkerd service mesh
it works well but suddenly sender app got too many cpu usage and in receiver app we have service
X.Y.svc.cluster.local:9090: http2 error: stream error received: stream no longer needed

what could be the problem !
grpc timeout in apps are 2 seconds
linkerd timeout in default value 10 secons
