Rocket.chat: Probable memory leak in server

[yuppox]

Description:

RocketChat server uses ever-increasing amounts of virt RAM. Res RAM seems more stable.

Over the course of ~30 days, virt RAM usage went from 6.2 GiB to 11.0 GiB.

Res RAM has gone up but it has also gone down.

Steps to reproduce:

1. Launch RocketChat server
2. Observe RAM usage over time

Expected behavior:

RAM usage remains within reasonable bounds.

Actual behavior:

Virt. RAM usage steadily increases over time and never goes down.

Eventually, it will crash with an out-of-memory error.

I suppose I should upgrade to the latest version. Are there any other steps to address the issue?

That's a good idea.

Weekly instances restart for now.

Thanks. That's what I was thinking - restarting weekly. I'll limit restarting to RC for now and see how it goes.

That's what I was thinking - restarting weekly

In my case I do full RC restart without any downtime.
I restart every single instance one-by-one in a 5 minute period for each.
Users from rebooting instances are spread across other instances.
And I do it in a most low traffic time (late night)
