title: Selenium WebDriver throws Timeout exceptions sporadically
body: <p>Using selenium for ui tests on our project. We are running the newest version 2.30.0.
  We use Firefox WebDriver and are running Firefox 19.0.</p>
  
  <p>Generally said the ui test works local and even server side when I run the ui test in Visual Studio. Our ui tests gets executed nighlty on our build server. It uses the same deploy on the same server I test manually via Visual Studio.</p>
  
  <p>But sporadically we run into following issue when the ui test gets executed on buildserver: </p>
  
  <pre><code>Test(s) failed. OpenQA.Selenium.WebDriverException : The HTTP request to the remote WebDriver server for URL http://localhost:7056/hub/session/bed1d0e7-efdc-46b6-ba07-34903519c44d/element/%7B8717bb19-96c7-44d3-b0ee-d4b989ae652d%7D/click timed out after 60 seconds.
        ----&gt; System.Net.WebException : The operation has timed out
         at OpenQA.Selenium.Remote.HttpCommandExecutor.CreateResponse(WebRequest request)
         at OpenQA.Selenium.Remote.RemoteWebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters)
  --WebException
     at System.Net.HttpWebRequest.GetResponse()
     at OpenQA.Selenium.Remote.HttpCommandExecutor.CreateResponse(WebRequest request)
  </code></pre>
  
  <p>Basically the test clicks on an upload button where the input field was filled with a file before. Since the file is very small this gets done in a few seconds.
  Nevertheless the timout of 60 seconds is reached sometimes.</p>
  
  <p>Any ideas how to isolate the underlying issue? Or run anybody into the same issue before?
  Any hints appreciated. Thanks.</p>
