Access Automation: Process won't quit

I'm saving a report to pdf from ASP.NET using this code:

Access.Application myAccessInstance = new Access.Application();

myAccessInstance.OpenCurrentDatabase("c:\\bugtest.accdb", true, "");

myAccessInstance.DoCmd.OutputTo(Access.AcOutputObjectType.acOutputReport,
"Overzicht", Access.Constants.acFormatPDF,
"c:\\Inetpub\\wwwroot\\AccessTest\\overview.pdf", false, null, null);

myAccessInstance.CloseCurrentDatabase();

myAccessInstance.Quit(Access.AcQuitOption.acQuitSaveNone);

Marshal.FinalReleaseComObject(myAccessInstance);
myAccessInstance = null;



After the quit the MSACCES process is still running.
(I have read: http://support.microsoft.com/default.aspx?scid=kb;en-us;317109)

How can I stop this process?
