Production build hangs after update to Meteor 1.6

I am experiencing inconsistent build issues after updating to Meteor 1.6 (though everything else about the version is great). On occasion, the build will hang, spiking my node process up to 2gb and taking up 140% of my CPU resources. Is anyone else experiencing this? I know it has been an issue in the past, but the old issues in Meteor’s github repo have been closed due to an inability to pinpoint the root cause. The packages our app is using include:

Have a look at my post here, go to the GitHub, check out the scripts there. You might find some tips or something you missed.

@SkyRooms Looks like you forgot the link. Can you add it in? Thanks
