We recently introduced Kong Ingress Controller into our dev env and it works fine. However, we noticed a much higher memory consumption on the kong pods and especially abnormal memory usage on the Nginx worker processes.
The kong which remains at version 1.1.2 without Kong Ingress Controller consumes ~300mb memory per worker process while handling much higher throughput.
However, the kong proxy pods with Kong Ingress Controller as control pods (kong version 1.5.1 and KIC version 0.7.1) consume much higher memory per worker process:
Has anyone encountered this issue before? What is your experience and suggestions on how can I debug it? Thanks!
