Hello Everyone
On running traffic (5600 tps) over application with istio injection I am getting below error in sidecar container of applications ingress-gateway for http2 inbound requests
It is either response 503 or response code 0 DC
Most of the requests (~70 %) to ingress gateway @ 5600 tps are failing.
