Do you see an OOM crash?
Nodejs typically consume more and more memory and isn't eager to run garbage collector so your chart doesn't necessarily mean it is leaking.

In my case. I set max memory per POD: 16Gb. I use docker k8s. It increases until stuck. Is there a way to reduce memory when nothing is running?

[jan_blaha]

Which process is using that memory? The nodejs?

Could you change the "templatingEngines.strategy=dedicated-process" so we know if the memory is used by the worker process or the main one?

I will try to set "templatingEngines.strategy=dedicated-process"

Hello.

This is the monitor of jsreport over 2 week. Any idea ?
Can you guess where the problem lies?
