title: Tracker-extract and Tracker-store processes consuming huge Amount of RAM
body: <p>I am using Arch Linux, kernel 3.16.</p>
  
  <p><em>From last one week my two processes tracker-extract and tracker-store are taking too much RAM. It results in hangup of system once in every 2 hours.</em></p>
  
  <p><strong>tracker-extract taking 300 MB and tracker -store taking 2 GB RAM.</strong>(total RAM is 3.8 GB)</p>
  
  <p>I want to know what are these tracker processes and what are their work.
  If i kill them does this effect in system performance ?</p>
  
  <p>What are the ways to kill them permanently so that I can get rid of these two processes?</p>
  
  <p>Please help me.</p>
