Kindly refer to attached Ethereal traces.
Host 172.29.10.210 initiates a TCP connection to host 172.16.76.20 on port 8081.
In the trace file "Port_58578_Good", the connection seems to be established and torn down normally.
In the trace file "Port_58703_Bad", the server initiates a FIN,ACK at which the client responds with an ACK. The client then sends a FIN,ACK but the server responds with an RST,ACK instead of ACK.
Is this normal? Users complain their connections have issue when we start to see these RST,ACK segments.
