title: chromedriver.exe hangs when running multiple test cases
body: <p>When I ran around 500 test cases in one <code>NUnit</code> session, some test cases were launching a blank browser and the test cases are failing. This issue is reproduced consistently. I googled a lot and found <a href="https://groups.google.com/forum/embed/#!topic/webdriver/tFS5MX6_B1Q" rel="nofollow noreferrer">this solution</a>, but it doesn't seem to be working.</p>
  
  <p>There are two error Messages as given below,</p>
  
  <ol>
  <li>chromedriver.exe stopped working.</li>
  <li>The HTTP request to the remote WebDriver server for URL session timed out after 60 seconds.</li>
  </ol>
  
  <blockquote>
    <p><strong>Specification</strong></p>
    
    <ul>
    <li>chromedriver version is = 2.22.397933 </li>
    <li>Google Chrome version is = 51.0.2704.106 m (64-bit) </li>
    <li>Nunit version = 3.4.1.</li>
    <li>Webdriver version = 2.53.1.0.</li>
    </ul>
  </blockquote>
  
  <p>What am I missing? Any help would appreciated.</p>
  
  <p>Below are the screenshots of the blank browser that gets open.</p>
