title: PHP memcached session expires out of the blue
body: <pre><code>session.save_handler = memcached
  session.save_path = "127.0.0.1:11211"
  session.gc_maxlifetime = 86400
  </code></pre>
  
  <p>The rest it standard. I expect the session to be kept alive for at least 86400 seconds since the last time user visited the page, ie If I started a session and visited page 5 minutes later, the session should expire only after another <code>86400</code> seconds.</p>
  
  <p>However, now session expires after roughly an hour. I've attached screenshot for the <strong>phpMemcachedAdmin</strong>.</p>
