Re: TCP server stop receiving new connections

Are you saying that you destroy your listening socket?

BTW, I'd also advise against using MFC sockets. And on
top of that, MFC only supports async socket model which
is not suitable for a server.

What do you do in your OnAccept handler? In particular,
do you try to accept multiple sockets? A test to try is to
reset the event mask of your listening socket each time you
exit its OnAccept handler.

Also, as a reality check - make sure your message loop
never gets stuck... E.g. when you break into the debugger,
almost always you should end up in the message loop.


Hi Alexander.

In OnAccept I just accept one incomming connection, since as documentation
of WSAAsyncSelect says, FD_ACCEPT is posted after an accept call if there
is another connection request available to accept. BTW, I have tested with
a loop in OnAccept handler to accept all pending connection requests and
behaviour did not change.

The problem is that OnAccept handler is not called for a long time (maybe
1, 2 or even 5 minutes).

OTOH, the first time I open the server socket, everything works fine, even
if there are 50 clients running trying to connect to the server before I
start the server. But after a shutdown/close/create/listen sequence the
problem appears. Maybe has something to do with the Socket Notification
Window creation/destruction by MFC framework?

Regards.
