"The underlying connection was closed" error

[GoogleCodeExporter]

Sandbox intermittently returns this error when you post carts from .NET code:

The underlying connection was closed: A connection that was expected to be
kept alive was closed by the server.

If the merchant-calculations part of the cart XML is removed this never
happens. If it's left in, the error above happens occasionally. I have
verified that the XML is valid. It is unclear if this is a problem with the
.NET code or with the Checkout Sandbox.

I can't reproduce it any more, but others can:

Adding myRequest.KeepAlive = false; in the Send() method of GCheckoutRequest 
doesn't
seem to hurt, and some say it helps. Will check in that change.

Alex reports this may help as well:
myRequest.ProtocolVersion = HttpVersion.Version10;

I tried both and always get the same error, I am using this code to post, 
mostly 
copied from the API, with some changes, the last line fails with:

The underlying connection was closed: Unable to connect to the remote server. 

I am connecting to the url at:
string.Format("https://sandbox.google.com/checkout/cws/v2/Merchant/{0}/request",

Merchant_ID)

ANY ideas  or pointers on how to find out what is going wrong, are greatly 
apretiated

thanks!

private string Send(string xml, string url) {
  System.Text.ASCIIEncoding  encoding=new System.Text.ASCIIEncoding();
  byte[] Data = encoding.GetBytes(xml);
  HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(url);
  myRequest.Method = "POST";
  myRequest.ContentLength = Data.Length;
  string authorization = "Basic " + GetAuthorization();
  myRequest.Headers.Add("Authorization",  authorization);
  myRequest.ContentType = "application/xml";
  myRequest.Accept = "application/xml";
  myRequest.KeepAlive = false;
  myRequest.ProtocolVersion = HttpVersion.Version10;
  Stream newStream = myRequest.GetRequestStream();

The error has not been reported in over two years. Closing the issue.
