title: Chromedriver out of memory
body: <p>I recently changed from PhantomJS to Chromedriver. When running chromdriver in Docker, after a while, I get the pod evicted with 'The node was low on resource: nodefs.' and I see using 'kubectl describe nodes' 'OOMKilling' and 'Memory cgroup out of memory: Kill process 452 (chrome) score 1867 or sacrifice child' . So I think this is a memory leak/memory issue. I am running my driver with:</p>
  
  <pre><code>    options = webdriver.ChromeOptions()
      options.add_argument('--disable-extensions')
      options.add_argument('--headless')
      options.add_argument('--disable-gpu')
      options.add_argument('--no-sandbox')
      options.add_argument('--incognito')
      options.add_argument('--disable-application-cache')
  </code></pre>
  
  <p>Is there anything else that I need to set/do?</p>
