I've got a node.js application that supporting React server rendering with communicating internal server API. BTW, application's RSS memory is increasing gradually.
I've been troubleshooting for 5 days now and already checked comparison of heap dump. But heap was stable. Only RSS was increasing.

At first, I thought that it causes from many client requests. However, today, I met huge traffic in short term. BTW, the RSS memory is not increased as much as traffic. It was strange.
I really wanna fix this issue. How and what should I do more?
