title: ADB crash constantly
body: <p>When i'm using Android Studio for hours (6-7) after a while the ADB becomes unstable. I mean it crashes random over and over again. It's 
  frustrating that my Nexus 7 is disconnected every time adb crash.</p>
  
  <p>It occurs every time when i'm using for hours. I tried with </p>
  
  <ul>
  <li>other cable</li>
  <li>plug into other USB ports</li>
  <li>restart Android Studio</li>
  <li><code>adb kill-server</code> and then <code>adb start-server</code> // fails</li>
  </ul>
  
  <p>Finally it always become unusable like this: <a href="https://i.stack.imgur.com/Q2oxB.gif" rel="nofollow noreferrer">http://i.stack.imgur.com/Q2oxB.gif</a></p>
  
  <p>As much as I can figure out only a system restart solves the problem but I think this isn't the proper solution for the problem. </p>
  
  <p>Anyone suffers the same problem? How can I solve this without system restart?</p>
