Node.js — Increase the Process’ Memory Limit

The system process of Node.js starts your applications with a default memory limit. If you’re going to run an application that saves a lot of data into variables and therefore memory, you may run into a Node.js process exit due to allocation issues.

The solution to run your Node.js app with increased memory is to start the process with an additional V8 flag: “--max-old-space-size”. You need to append your desired memory size in megabytes.

The following command will start the server.js with a memory limit of 8 GB.

► node --max-old-space-size=8192 server.js
