title: What's the meaning of "Internal" in "!heap -h" output in windbg?
body: <p>I am following this stackoverflow post
  <a href="https://stackoverflow.com/questions/6687414/what-do-the-different-columns-in-the-heap-flt-s-xxxx-windbg-command-represe">What do the different columns in the &quot;!heap -flt -s xxxx&quot; windbg command represent</a></p>
  
  <p>I am trying to understand the information printed out for one of the heaps that using up a lot of memory.</p>
  
  <p>I can understand most of the columns but on my windbg, I see an additional column.  Most of my entries are marked as <strong>Internal</strong>.  I wonder what that means.  I have done <code>!gflags +ust</code>.  So, I can see the call stack for making the memory allocation.  I can do it on most of the entries except the ones marked as <strong>Internal</strong>.</p>
  
  <p>What does <strong>Internal</strong> mean? Is it something related to the implementation of LFH?  If this is the internal implementation of LFH, how and when will these <strong>Internal</strong> heap entries return to the free list?  It's holding up my memory for no reasons now.</p>
  
  <p>Here is the output of <code>!heap -h 0000000002330000</code> for your reference.</p>

  <p><strong>EDIT 10/26/2012</strong></p>
  
  <p>I finally found out the place that causing the leak, by inspecting the memory content inside the <strong>Internal</strong> heap entry.  It contains a number of memory allocation caused by the same <code>operator new</code>.  I don't know why they are all combined into one single heap entry but by looking at the content, I managed to find out the code causing the leak.  Perhaps, it's a CRT feature to combine all similar data into one heap entry?  Or do I misunderstand the meaning of heap entry completely?</p>
