title: ThrottleService(79): unable reading network stats
body: <p>I am getting Exception <code>" ThrottleService(79): problem reading network stats"</code><br>
  I don't know why this is giving me exception and in the App there is some communication with server which is working fine but the XMPP packet listener which was working in past, is not working now. Can anybody tell me what is wrong ?<br>
  Please help me, Thanks in advance.</p>
  
  <p>The XMPP shows the device is logged in and is online on server.</p>
  
  <p>My environment :</p>
  
  <h1>Server Side :</h1>
  
  <p>OS :Windows<br>
  XMPP Server : Openfire 3.7.1.<br>
  Apache tomcat 6<br>
  Java 6 </p>
  
  <h1>Client side :</h1>
  
  <p>Android 4.0.3<br>
  For XMPP I am using Smack Library   </p>
  
  <p>What should I do? I am stuck to this point.</p>
