Connection reset by peer issue with SSL OAuth Proxy when route objects are created more than 80.

When routes are created more than 80, SSL connections between OAuth Proxy container and HAProxy are disconnected with the following error messages

2022/12/15 21:37:01 server.go:3120: http: TLS handshake error from 10.128.18.27:47142: write tcp 10.128.10.57:8443->10.128.18.27:47142: write: connection reset by peer 

With Model serving with 100 connections made OAuth proxy container failed so model serving pod failed too.

Always

Disconnected connections between OAuth Proxy and HAProxy

No errors happen

When I set replica of Router to 1, the issue was gone. However, if I increased it to 3, the issue was still around. So I don't think it is resource limitation issue.
