Tools to map threads to their memory usage?
<p>Having some performance issues in a Weblogic 11g production system. </p>

<p>As part of the debugging effort, I’m interested in finding a way to map threads to their memory usage, then seeing the stack to determine what part of the application is consuming so much.  </p>

<p>Anyone know of a tool or method to do what I want to do?</p>

<p>I'm not interested in JProbe memory profiling as it requires too much overhead (taking snapshots of everything). Also, I've read about Heapwalker in NetBeans that seems promising.</p>
