SaveBinaryDirect error

Every time I try to upload a 10.1 MB file I am getting this error:

ex = {"The underlying connection was closed: An unexpected error occurred on a receive."}

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.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)

   at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead)

I have tried KeepAlive=false, changing the max upload size in sharepoint and IIS, changing the request timeout and the maxservicepointidletime.
