w3wp.exe eats all memory in IIS usin Response.BinaryWrite

I have this site, written in ASP which makes intensive use of Response.BinaryWrite, this is the code mostly used (Jscript):

  var rs = cn.execute(sqlQuery)
  var pos = 0;
  var binMem = rs(0); // data is in first field of recordset

  var stream = Server.CreateObject("ADODB.Stream");
  stream.Type = 1 //adTypeBinary
  stream.Open();
              
  Response.ContentType = this.getContentType();
  Response.AddHeader("Content-Disposition", "inline;filename=\"" + filepath + "\"");
  Response.Buffer = false;
  stream.Write(binMem.Value);
  stream.Position = 0;
  var buffer = (16 * 1024);
                
  while (!stream.EOS)
  {
    Response.BinaryWrite(stream.Read(buffer));
  }
               
  stream.Close();
  try { rs.close(); rs=null; dbe.close(); dbe=null; } catch (e) {}
             
After a few hours the w3wp.exe eats all the system memory (about 1,3Gb) and w2k3 starts paging, which cause IIS to start responding very slowly.

I have read there's a fix from microsoft here:
http://support.microsoft.com/kb/916984

but i have also read that it doesn't completely solve the problems because one of the side effects of applying the fix is that IIS hangs up occasionally.

It would be nice to hear from someone that streams large files using Response.BinaryWrite without having those problems, and to know how he/she does it. I was wondering if using small reads from the record and small writes to the stream could avoid this problem.
