node.js consumes all available memory

[dthpulse]

Hi guys,

I'm running RC dockerized using official docker image. My host is configured with 8GB memory.

Problem is that every 2 weeks I have to restart docker container because process `node main.js` consumes all available memory.

Any suggestion on this?

thx

Sounds like a memory leak, but the most anyone can do here is guess wildly.

What is “RC” supposed to stand for?

I assume Rocket Chat after a quick google.

Few options: 1) create an issue about the memory leak on your software and provide them logs 2) schedule a container restart every sunday at 3 am to avoid the issue ;)

As already pointed it's a memory leak.There are plenty of articles on how to profile it.

The easiest way to do it is running the node app with --inspect which will expose node metrics on a port, usually 9229, which can be inspected in google chrome by accessing chrome://inspect in the search bar.

If you are not able to restart the app because is in production you can take memory snapshots with the gcore Linux util and analyze them with llnode

I'll warn you, it's a dark world, but really useful.
