Hi everyone, I would like to know if anyone knows the reason why I get a lot of connections (more than 100) from the same IP in FIN_WAIT_2 state. Refering to this diagram (http://www.jxos.org/Projects/TCP/tcpstate.html), the connection enter in FIN_WAIT_1 when the server closes the connection and in FIN_WAIT_2 when the client ACK the FIN from the server. For the connection to stay in FIN_WAIT_2, the client must never send his FIN, right? In this case the connections are on port 80. Is it a problem with the client's browser or OS? Is it possible that some mobile devices doesn't close their connections correctly to save bandwidth and battery? I know this isn't specific to FreeBSD, but thanks for your answer anyway Martin
