title: Crash with "Out of Virtual Memory"
body: <p>I'm maintaining an existing application and I've encountered a bug when running under some conditions (easily reproducible), where the app fails with message : </p>
  
  <ul>
  <li>Title: "Windows - Out of virtual memory"</li>
  <li>Content: "Windows is low in virtual memory..."</li>
  </ul>
  
  <p>Question is: what I need to check first? When is this message happening? Why?</p>
  
  <p>What is stored in this virtual memory in C#, why an out of memory?</p>
