You're putting more context behind that than there really is - the reader may, for example, have read all the data, but never have issued the close() call. > and the reading side never closes the socket. "Has not yet closed" :-). http://www.cs.northwestern.edu/~agupta/cs340/project2/TCPIP_State_Transition_Diagram.pdf (itself reproduced from "TCP/IP Illustrated, Volume 2") is a useful resource if you want to know what the states mean. If you're seeing CLOSE_WAITs on the Tomcat server, it means the client has sent a FIN and Tomcat's ACKed that. If you can, look on the client to see what's happening. If you see connections in FIN_WAIT_1, the client never got the ACK from Tomcat, if you see connections in FIN_WAIT_2, the client got the ACK and is sitting around waiting for Tomcat to close the connection and send a FIN. - Peter P.S.
