Comment 3 for bug 1823803

I reproduced this issue with my deployment, simplex(two Intel(R) Xeon(R) Gold 6139 + 192G memory). There are three ingress controller pods. In each pod, there are one ngnix master process and 72 worker processes. In total, all nginx processes in the three pods consumed ~8G memory. I am working on a patch to modify nginx configuration.
