Node cpu usage at >50% on idle

[brettg2]

We noticed this a few weeks ago and have yet to find a solution. Could this be something inherit with node? Would we need to downgrade Meteor? We are currently running Meteor version 1.5.1 on Windows 7 and 10 environments (plain cmd prompt).

Lastly, we don't have any server side code. The majority is front-end with an ajax call to our .NET/SQL backend.

Let me know if you need other information. Your help is greatly appreciated. Thank you!
