Out of memory with npm run build

Question

I have a react project, about 40MB. I run 'npm run build' with the param --max-old-space-size=4096.

At my local, about 8GB RAM, the build is running fine. But on Jenkins (AWS EC2 hosted one, t2.medium) 4GB, either 'Out Of Memory' or crash EC2 instance.

Please advice if any way we can overcome on Jenkins 4GB RAM.

Thanks,

You should also check if there aren't any other apps eating out the memory on that EC2 instance. Because the react build itself, consuming 4 GB of memory, in a small project, is much unlikely to happen!
