title: Huge anon blocks in pmap
body: <p>I am doing a pmap on a tomcat process and I am seeing some huge anon blocks. From what I read anon blocks are used for thread stacks and for JNI. I have a very moderate thread count. How can I go about finding out what is causing these huge anon blocks?</p>

  <p>( on  a side note is pmap the correct way to measure how much memory is allocated to tomcat?) </p>
