Ethereal trace : Possible abnormal closing of a TCP connection

Hi Sir,

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.

Please advise.

Thank you.

B.Rgds,

Lim TS
