title: Why connection is terminating
body: <p>I'm trying a random forest classification model by using <code>H2O</code> library inside R on a training set having 70 million rows and 25 numeric features.The total file size is 5.6 GB.</p>
  
  <p>The validation file's size is 1 GB.</p>
  
  <p>I have 16 GB RAM and 8 core CPU on my system.</p>
  
  <p>The system successfully able to read both of the files in H2O object.</p>
  
  <p>Then I'm giving below command to build the model:</p>
  
  <pre><code>model &lt;- h2o.randomForest(x = c(1:18,20:25), y = 19, training_frame = traindata, 
                            validation_frame = testdata, ntrees = 150, mtries = 6)
  </code></pre>
  
  <p>But after few minutes (without generating any tree), I'm getting following error:</p>
  
  <blockquote>
    <p>"Error in .h2o.doSafeREST(conn = conn, h2oRestApiVersion = h2oRestApiVersion, : Unexpected CURL error: Recv failure: Connection reset by peer"</p>
  </blockquote>
  
  <p>However If I tried above code with 1 tree, its running successfully.</p>
  
  <p>Is the above error occurring because of memory issue? Any help will be appreciated.</p>
