title: Problems to run examples in Meteor
body: <p>I'm testing Meteor examples and this is what I see when I run <code>meteor</code> in todos examples:</p>
  
  <pre><code>Unexpected mongo exit code 100. Restarting.
  Unexpected mongo exit code 100. Restarting.
  Unexpected mongo exit code 100. Restarting.
  Can't start mongod. Check for other processes listening on port 3002 or other meteors running in the same project.
  </code></pre>
  
  <p>And this is what happens if I run <code>mongod</code> in the command line:</p>
  
  <pre><code>Thu Apr 12 19:27:39 Mongo DB : starting : pid = 2686 port = 27017 dbpath = /data/db/ master = 0 slave = 0  32-bit 
  
  ** NOTE: when using MongoDB 32 bit, you are limited to about 2 gigabytes of data
  **       see http://blog.mongodb.org/post/137788967/32-bit-limitations for more
