rojkov commented 2 years ago

I don't really understand what is wrong exactly (Envoy doesn't close a connection when the peer resets it?) and where Envoy is sitting in this setup.

Perhaps @alyssawilk @lizan could help.

alyssawilk commented 2 years ago

if Envoy is setting up for a connection close and not sending a FIN could it be because of the delay close? have you tried turning that delay down and seeing if it helps?

cobb-tx commented 2 years ago

@rojkov sorry I describe is not very clear. the peer resets it， probably because the envoy （istio-ingress）close connection without FIN I guess。 and This is by intermittent

cobb-tx commented 2 years ago

@alyssawilk i will try it. I tried before timeout and keeplive but It's not working

cobb-tx commented 2 years ago

i will close this issue because this bug not envoy，it is kube-proxy problem and i will The process of troubleshooting a problem in next

cobb-tx commented 2 years ago

i find this can fix this bug but incomplete because There will be more 502

ipvsadm --set 7500 120 300

and we consider k8s-ingress（nginx） keeplive 75s There's reason No 502， i will test envoy timeout 75s
