The error:

You can try changing the amount of memory node uses with this command: node ----max-old-space-size=1024 yourscript.js

--max-old-space-size=1024 will allocate 1 gig of memory.

By default node will use 512 mb of ram but depending on your platform you may need to allocate more or less so the garbage collection kicks in when you need it.

If your platform has less than 500 mb of ram available then try setting the memory usage lower to --max-old-space-size=256.
