Uploading sharepoint document exception using SaveBinaryDirect

Question

I have a Windows Application that saves .pdfs to a SharePoint Document Library. It works fine except this one file. Whenever I use SaveBinaryDirect with this 10.1MB file I get the following exception:

System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An established connection was aborted by the software in your host machine. ---> System.Net.Sockets.SocketException: An established connection was aborted by the software in your host machine
   at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags)
   at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)
   --- End of inner exception stack trace ---

   at Microsoft.SharePoint.Client.File.SaveBinaryDirect(ClientContext context, String serverRelativeUrl, Stream stream, Boolean overwriteIfExists)
   at BKWatch.BKWatchViewModel.UploadDocument(String siteURL, String documentListName, String documentListURL, String documentName, Byte[] documentStream, Int64 AccountId, String DebtorName, Nullable`1 Pages, String Title) 

I have already tried the following:

clientContext.PendingRequest.RequestExecutor.WebRequest.KeepAlive = false;

System.Net.ServicePointManager.MaxServicePointIdleTime = 600000;
 clientContext.RequestTimeout = 600000;

Increasing max size in SharePoint - already at 50 MB Increasing max size in IIS web.config - Already at 2GB

Thanks.

Well after a couple long phone conversations with Microsoft, they think there is a bug in the SaveBinaryDirect code and recommended I use the ClientObject.Add functionality instead. Seems to be working so far.
