title: Mongoimport out of memory(?) at 2 GB of an import
body: <p>So I'm trying to import 2.3 gb of JSON into Mongo using Mongoimport. After reaching 2 GB the import stalls, freezes, and kills my machine. </p>
  
  <p>After looking around and finding lots of stuff about namespace issues, I tried to fix the problem by making sure I had the most recent 64bit build, but this fixed nothing. </p>
  
  <p>Then I tried to import it while running Mongod with WiredTiger, which should, if I remember correctly, only function in a 64 bit environment anyway and enforce those conventions by default. Nope. </p>
  
  <p>Whatever I do, the import always seems to fail at 2 GB and I get no error messages.</p>
  
  <p>Is there a workaround or solution for importing datasets greater than 2 GB?</p>
