title: Trying to locate a leak! What does anon mean for pmap?
body: <p>I'm trying to locate where my memory has gone for a java process running in linux. Someone suggested I use pmap -x to see exactly what the memory is doing. </p>
  
  <p>The output is really long but basically a good portion of it is a repeat of this:</p>
  
  <pre><code>00007fbf75f6a000    1016       -       -       - rwx--    [ anon ]
  00007fbf76068000      12       -       -       - -----    [ anon ]
  </code></pre>
  
  <p>What exactly does this mean? Why do I have so many entries of this (4000+)?</p>
