Hi,
I am (for now) ignoring this line as it exists before exit and after:
tcp 0 0 127.0.0.1:56901 127.0.0.1:10027
TIME_WAIT
Apart from that the acceptor tcp ports have been closed (as there is no
LISTEN in your second output.
As for the remaining session (the 2 listings are the same session):
If you use close(true) then the traditional close handshake (FIN -->
FIN-ACK) does not take place in the correct way.
Thus this would leave the port in the CLOSE_WAIT and other end FIN_WAIT2
state.
To solve this you normally use close(false) and wait for the session to
shutdown gracefully.
You could built in a sleep of a few seconds to give the system the time
to close the sessions.
I haven't found a better way of doing this than doing a close(false) on
all sessions, wait for example 30 seconds, and then a close(true).
If anyone has a better way of handling this let me know as I cannot find
a good way to handle these situations all over the internet.
Maybe Emnanuel has a good solution for this.
Hope my comments help you....
Regards,
Mike

Hello,
thanks for the suggestion - i tried it out but it does not seem to work - the
server listener port is closed (this worked for me before) however the client
who connects still has the sessions opened. After doing a close(true) on all
sessions - and confirming with acceptor.getManagedSessions().size() that there
are indeed 0 sessions left - im puzzled who is to blame - the mina server or
postfix ?
Here is the netstat output after at least one session has been created
(there are 2 mina services running, at 10027 and 10028)
tcp 0 0 127.0.0.1:10027 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:10028 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:54751 127.0.0.1:10028 ESTABLISHED
tcp 0 0 127.0.0.1:56901 127.0.0.1:10027 TIME_WAIT
tcp 0 0 127.0.0.1:10028 127.0.0.1:54751 ESTABLISHED
after i shutdown the server and a debug output confirmed that the address was
unbind, and 0 sessions are left - im left with this
tcp 1 0 127.0.0.1:54751 127.0.0.1:10028 CLOSE_WAIT
tcp 0 0 127.0.0.1:56901 127.0.0.1:10027 TIME_WAIT
tcp 0 0 127.0.0.1:10028 127.0.0.1:54751 FIN_WAIT2
the client is still connecting to 10027 and 28, and for some reason the server
port for 10028 is still open but on fin_wait2.
I also tried adding acceptor.dispose(); after unbind - no dice.
Any further ideas?
Thanks
