osx-ulimit

Darwin (OS X kernel) has a low limit for file descriptors (256 per process) by default.

When you try to open more file descriptors than this, an exception is thrown.

This is a simple library that allows you to easily raise this limit manually for the running process.

Node.js 0.12 joyent/node@6820054 has a proper fix so you hopefully won't need it for when it's released as stable.

Warning

It still requires you to manually invoke something like launchclt limit maxfiles 10000 10000, otherwise it won't make any difference. You'll have to run this command as a system administrator / root. Do yourself a favor and read the reference. You can't turn the limit higher without invoking it with the right permissions or it'll just silently ignore it. To verify your limit use launchctl limit maxfiles.

Install

npm install osx-ulimit

Usage

require('osx-ulimit').set(); // Defaults to 30000

or

require('osx-ulimit').set(threshold);

To get the current ulimit

require('osx-ulimit').get();

If not on OSX, the above will be undefined.

The threshold should be an integer number with the minimum soft limit of file descriptors you want. Default: 30000.

Tests

Run nodeunit.
