Limiting node.js's memory usage

https://github.com/joyent/node/wiki/FAQ

What is the memory limit on a node process?

Currently, by default v8 has a memory limit of 512mb on 32-bit systems, and 1gb on 64-bit systems. The limit can be raised by setting --max_old_space_size to a maximum of ~1gb (32-bit) and ~1.7gb (64-bit), but it is recommended that you split your single process into several workers if you are hitting memory limits.

Value is in megabytes, I believe.

It's now, --max-old-space-size no technology limits...

for example node --max-old-space-size=8192 ./app. We create limit in 8Gb
