Application sends RSTs abruptly and thus fails to complete.

This is happening always for a particular application on a specific client.

The application is unable to complete and "network communication error" pops up. In one run log shows: "java.net.SocketException: recvfrom failed: ECONNRESET (Connection reset by peer)" Corresponding pcap shows client sending RSTs after sending 15 Dup Acks for the same packet.

In another run log shows : "java.io.IOException: unexpected end of stream" Corresponding pcap shows 16 Dup acks for same packet which is then recieved afterwards. Client sends 2 "tcp windows update" msgs after that.It then sends [FIN,ACK] and then starts sending RSTs.
