Short description of the problem:

Every few minutes 'ionic serve --lab' will crash with this error:

Steps to reproduce:

1. run 'ionic serve --lab'
2. make code changes
3. sometimes it will crash, every 5 minutes or so

Cordova CLI: 6.3.0
Gulp version: CLI version 3.9.1
Gulp local:
Ionic Framework Version: 2.0.0-rc.0
Ionic CLI Version: 2.1.0
Ionic App Lib Version: 2.1.0-beta.1
OS: Distributor ID: Arch Description: Arch Linux
Node Version: v6.7.0

Happening from me as well, without the --lab flag. Its related to a memory leak what Node complain about every time when ionic serve re-compile the source files.
