it should still fix some issue Have you enabled tracing on both sides (server and client)? You should see the source of the error in one of the tracefiles. My guess are that you may have to increase some values of the XmlDictionaryReaderQuotas.

This might help you MPI_Bcast() is a collective function, which means that every process in the communicator must call it. In other words, don't call MPI_Recv(). So get rid of your if(myrank == 0) conditional and have all processes call: code :
MPI_Bcast(vec,W,MPI_INT,0,MPI_COMM_WORLD);

hope this fix your issue try to use wireshark to see what the exact issue and why is it persisting. basically, it means that the remote side closed the connection (most commonly happens during TCP/IP RST packet) and the reason can vary:

Does that help I think I solved my own issue. Since I have the exception triggered when sending data and the endpoint is off or not connected, I should check if it is connected or not before sending the data. However, there is no straight forward way to find if the endpoint is connected. Since when I send data and the endpoint is off it triggers exception, the exception became my indicator that the endpoint is off and connection is lost. So what I do is that I create the Socket again within the "Catch" statement and try again every period of time until the Socket is connected again. code :
private void MessageCallBack(IAsyncResult aResult)
{
try
{
int size = sck.EndReceiveFrom(aResult, ref epRemote);
if(size>0)
{
byte[] receivedData = new byte[1500];
receivedData = (byte[])aResult.AsyncState;
ASCIIEncoding eEncoding = new ASCIIEncoding();
string receivedMessage = eEncoding.GetString(receivedData);
listBox1.Invoke(new MethodInvoker(delegate {
listBox1.Items.Add("From a friend: " + receivedMessage); }));
}
byte[] buffer = new byte[1500];
sck.BeginReceiveFrom(buffer, 0, buffer.Length, SocketFlags.None,
ref epRemote, new AsyncCallback(MessageCallBack), buffer);
}
catch(Exception exp)
{ /* here is the solution, when the Catch is triggered, close the
socket and recreate it to avoid the issues that I been having of
not sending messages and instability. I also added some functions
that would keep sending the status and //being checked on the other
side in order to keep online/offline status.*/
sck.Close();
sck = new Socket(AddressFamily.InterNetwork, SocketType.Dgram,
ProtocolType.Udp);
sck.SetSocketOption(SocketOptionLevel.Socket,
SocketOptionName.ReuseAddress, true);
connectEndPoint();
//MessageBox.Show("Exception Small Chat: " + exp.ToString());
}
}
