use IO::Select;

                        print "tcp write timeout" && next if !$sel->can_write(1);

                        $socket->close();

                        chomp($server_state);

                        if ($server_state <= ($servers->{$server}->{max_jobs} + 3) ) {
                                push(@good_servers, $server);
                        } else {
                                print "$server returned $server_state...\n";
                        }

                }

        }

this is giving me:

IO::Socket: Cannot configure a generic socket at ./xxxxxxx line 1407

any ideas why? $server is valid host address.
