title: WPF d3d9.dll crash
body: <p>I have several applications in WPF that periodically crash on 2 different servers (a dell poweredge and a HP proliant). The problem is that the WPF applications both crash within d3d9.dll. Rebooting the servers always fixes the problem. The problem only occurs a few times a month. Both servers are running Windows XP instead of Windows 2003.</p>
  
  <p>Here is the event viewer application log entry for the crash</p>
  
  <pre><code>Faulting application iqlayer.exe, version 5.3.1.14, stamp 4a9d0d63, faulting module d3d9.dll, version 5.3.2600.2180, stamp 41109693, debug? 0, fault address 0x0003a756.

  </code></pre>
  
  <p>Once this problem occurs, all further WPF applications will not run until I reboot. I even tried running a test application which showed a blank window. The test app crashed immediately on start at d3d9.dll.</p>
  
  <p>I found this <a href="http://support.microsoft.com/kb/967581" rel="nofollow noreferrer">KB</a> which i think is related to my problem. However, i didnt install directX SDK on my server and dont know where to uncheck "Break on D3D9 Error".</p>
