<p>Sometime, I have a error:</p>

<blockquote>
  <p>Message The handle is invalid. (Exception from HRESULT: 0x80070006 (E_HANDLE))</p>
  
  <p>StackTrace at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo) at System.Web.Util.Misc.ThrowIfFailedHr(Int32 hresult) at System.Web.Hosting.IIS7WorkerRequest.GetBufferedResponseChunks(Boolean disableRecycling, ArrayList substElements, Boolean&amp; hasSubstBlocks) at System.Web.HttpWriter.FilterIntegrated(Boolean finalFiltering, IIS7WorkerRequest wr) at System.Web.HttpResponse.FilterOutput() at System.Web.HttpApplication.CallFilterExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean&amp; completedSynchronously)</p>
