We got the following SocketException (for secure socket) during a socket receive operation.

A first chance exception of type 'System.Net.Sockets.SocketException' occurred in system.dll

Additional information: An established connection was aborted by the software in your host machine

=====

The server side is sending an xml stream of about 80k bytes and immediately closes the socket after the stream is sent. The client side receives the data ok until its last receive operation -- the socket is closed during the receive operation, thus the exception. If I put a delay (2 sec) on the server side before it closes the connection, then the client is ok.

Note that if I use normal network stream, then the exact same query works fine WITHOUT the delay.

QUESTION IS: how do we get the client to handle the close normally with the receive operation?

Is it possible for the client to know all data has been received and completes the read before process the close?

Are you also using the Security Library on the server side? If so, how do you close the connection? Do you simply call Close of do you call Shutdown first. If you do not call Shutdown first, the connection is abruptly terminated and this may result in the SocketException you're seeing on the client side.
