Hello Alessandro
The two ways you mentioned I have tried.But it doesn't work yet.
Yes,It's 4 sure only on Unix.But I haven't tried MINA 1.0 cause the
ex-server built on MINA 0.9.4 is running public,which cannot be stopped by
will.
I will try later
Best Wishes
James Ling

Subject: Re: Question About Port Stucking(It has troubled me 4 a very long
term)
I have this problem only on Unix machines (Linux and MacOsX)...
I added this code for shutdown, tonight I will try also to explicitly
close
all the sessions (now I don't have a linux machine to try it)...
// shutdown bug on unix machines (found on linux / mac os x)
Runtime.getRuntime().addShutdownHook(new Thread() {
// This method is called during shutdown
@Override
public void run() {
socketAcceptor.unbindAll();
System.exit(0);
}
});
So i will add this few lines:
@SuppressWarnings("unchecked")
Set<IoSession> sessions = socketAcceptor.getManagedSessions
(serverAddress);
for (IoSession session : sessions) {
session.close();
}
the complete code:
// shutdown bug on unix machines (found on linux / mac os x)
Runtime.getRuntime().addShutdownHook(new Thread() {
// This method is called during shutdown
@Override
public void run() {
socketAcceptor.unbindAll();
@SuppressWarnings("unchecked")
Set<IoSession> sessions = socketAcceptor.getManagedSessions
(serverAddress);
for (IoSession session : sessions) {
session.close();
}
System.exit(0);
}
});
