How can I restart a node process once it reaches a certain memory size (leak)?

Question

I have a memory leak in a Node.js, and I'm working on trying to find it but it's currently deployed to Heroku. I'd like to currently have something that would restart the process once it reaches a certain size in memory (especially since I have a few dynos running).

Answer 1

Do you use PM2 to run your app? If yes there's a good config option that fits your need called max_memory_restart.

Answer 2

Not finding a solution I created a npm utli lib that does that. Please note it does not work on windows though.

It's based on cluster and status npm libs.
