Hello Youcef,

I never seen this error - it is triggered in the following code in WWSympa 
CGI script:

    $session = Sympa::Session->new(
        $robot,
        {   'cookie' =>
                Sympa::Session::get_session_cookie($ENV{'HTTP_COOKIE'}),
            'action' => $in{'action'},
            'rss'    => $rss,
            'ajax'   => $ajax
        }
    );

    # Getting rid of the environment variable to make sure it won't be
    # affected to another anonymous session.
    undef $ENV{'HTTP_COOKIE'};
    unless (defined $session) {
        Sympa::send_notify_to_listmaster($robot,
            'failed_to_create_web_session', {});
        wwslog('info', 'Failed to create session');
        $session = Sympa::Session->new($robot, {});
    }

Sympa looks up the cookie provided by the user in the table "session_table". 
So this message would
be triggered by a bogus / broken cookie.

Regards
         Racke
