title: Unable to open more than five Chrome browers with Selenium
body: <p>I launch the hub and node:</p>
  
  <pre><code>java -jar C:\...\selenium-server-standalone-2.25.0.jar -role hub
  java -jar C:\...\selenium-server-standalone-2.25.0.jar -role node 
      -hub http://localhost:4444/grid/register 
      -browser browserName=chrome,maxInstances=6,platform=WINDOWS 
      -timeout 0
      -Dwebdriver.chrome.driver=c:\...\chromedriver.exe
  </code></pre>
  
  <p>Then, I create Chrome driver instances:</p>
  
  <pre><code>    Dim desiredCapabilities As Remote.DesiredCapabilities = Remote.DesiredCapabilities.Chrome()
      Dim size As String = "--window-size={0},{1}"
      size = String.Format(size, browserWidth, browserHeight)
      Dim position As String = "--window-position={0},{1}"
      position = String.Format(position, browserWidth * index, 0)
      desiredCapabilities.SetCapability("chrome.switches", {size, position})
      driver = New Remote.RemoteWebDriver(New System.Uri("http://localhost:4444/wd/hub"), desiredCapabilities)
  </code></pre>
  
  <p>Five works fine. The sixth times out waiting for Selenium to respond. Here is the error:</p>
  
  <pre><code>OpenQA.Selenium.WebDriverException: No response from server for url http://localhost:4444/wd/hub/session. Aborting test execution.
  </code></pre>
  
  <p>There is no activity in the node, so it appears the hub is not allocating the sixth request to the node. Is there a setting other than <code>maxInstances=6</code> that I need? </p>
