title: Eclipse uses 100 % CPU randomly
body: <p>My eclipse sometimes starts using 100 % of my CPU very spontaneously.
  I can't figure out why it needs that much CPU usage. There is no background task like "building workspace" running.</p>
  
  <p>After some time the CPU load drops to 0 and everything is normal.</p>
  
  <p>I can't find any information related to the problem in <code>workspace/.metadata/.log</code> file.</p>
  
  <p>Has anybody some tip how I can figure out which part of eclipse is using the CPU so heavily? Is there a way to get a thread dump of eclipse? The <code>kill -3</code> on the eclipse process doesn't do anything.</p>
  
  <p>Eclipse Version: Galileo JavaEE<br />
  Operating System: Linux 2.6.31</p>
