标题: A lot of sockets in CLOSED status [打印本页] 作者: yanzt 时间: 2003-11-13 18:42 标题: A lot of sockets in CLOSED status We have met a very amazing problem on SCO unixware 7.1.3. The weblogic run on it and listen on ssl port. After running for some time, a lot sockets will list as CLOSED status. From rfc 793, the CLOSED status of TCP represents no connection state at all.
So the sockets should be released. But why it list such status when use netstat? Is it a OS problem or TCP parameter tunning problem?
Any idea is welcome!
Thanks a lot!

He told me that if he use netstat, it will list a lot of sockets whose status is CLOSED. From RFC793, the CLOSED status is a fictional status, so it should not list in netstat status list and all the sockets in such status should release the file descriptors it used. I think it may be a os bug or something. I haven't seen such status in other OS type such as AIX and HP Unix. If the status is CLOSE_WAIT, we can tune the tcp_2msl parameter of TCP. But for such status, I can not find a way to fix it. The SCO engineers can not give a reason for it too.
Any one met such problem before?
