Please note that because you used the base "phantom" library from npm it won't ever work with cluster (because node doesn't do the right thing with port=0 under cluster). You'd have to switch to node-phantom-simple. Which might be worthwhile anyway because the phantom library you've used proved massively unstable at scale for us - I wrote it because of the need to work under cluster, and because dnode communication was bloated and unstable.
