node.js — отправка 250 мс UDP-цены за соединение через сокет из C ++ к сбоям процессов nodejs, почему?

Попытка отправить ценовые тики UDP от процесса «говорящего» в C ++ процессу «слушателя» nodejs, и я получаю сбой.

Разговор тика и слушание работают для процессов C ++ — C ++. Когда я добавил слушателя части Nodejs, он взорвался.

Любое понимание? Спасибо, Кит: ^)

Данные тика Выглядит хорошо:

Price unicasted: 49.58
Price unicasted: 50.00
Price unicasted: 50.24
Price unicasted: 50.09
Price unicasted: 49.81

C ++ Talker

#define SERVERPORT "4950"
int main(int argc, char *argv[])
{
int sockfd;
struct addrinfo hints, *servinfo;
int rv;
size_t numbytes;
char* address = "192.168.1.100";

memset(&hints, 0, sizeof hints);
hints.ai_family = AF_INET;
hints.ai_socktype = SOCK_DGRAM;
hints.ai_protocol = 0;

if ((rv = getaddrinfo(address, SERVERPORT, &hints, &servinfo)) != 0) {
fprintf(stderr, "getaddrinfo: %s\n", gai_strerror(rv));
return 1;
}
sockfd = socket(servinfo->ai_family, servinfo->ai_socktype, servinfo->ai_protocol);

char myPrice[7];
float f;
while(1) {
f = randPrice();
ftoa(f, myPrice, 2); // Convert price to string
myPrice[5] = '\n'; myPrice[6] = '\0';

std::cout << "Price unicasted: " << myPrice;
if ((numbytes = sendto(sockfd, myPrice, strlen(myPrice), 0, servinfo->ai_addr, servinfo->ai_addrlen)) == -1) {
perror("talker: sendto");
exit(1);
}
std::this_thread::sleep_for(std::chrono::milliseconds(250));
}
freeaddrinfo(servinfo);
close(sockfd);

return 0;
}

Node.js Listener

var PORT = 4950;
var HOST = '192.168.1.100';

var dgram = require('dgram');
var server = dgram.createSocket('udp4');

server.on('listening', function () {
var address = server.address();
console.log('UDP Server listening on ' + address.address + ":" + address.port);
});

while(1) {
server.on('message', function (message, remote) {
console.log(remote.address + ':' + remote.port +' - ' + message);
});
}

server.bind(PORT, HOST);

ошибка Ик!
