No ideas. It's the problem of your server and not of the socket. Or
maybe it is the problem of your client. Post the code, maybe someone
will point it out for you. Usually you never should use SO_LINGER,
unless you know exactly what you are doing (it is not your case).
Also try to get the Stevens book "Unix Network Programming" and learn
how to handle abnormal terminations of TCP connections (I assume you
pass data using TCP).
