Thank you for your reply. I don't have any child thread. What I have is in
the OnInitDialog() of my main dialog ( I have a dialog based application) I
create a new class, that have a member variable derived from CAsyncSocket,
with new operator and call a method Init(), that will create the socket.
The assert appears very occasionally and is very hard to reproduce.

Thank you,
Adrian
