IRC Socket - Stop receiving after 2 minutes

Hi guys!

Someone can tell me why after about 2 minutes I stop receiving data? I see all the connection reply from the server, the bot join the channel, I can talk to him in private or in channel but if I wait about 2 minutes then.. nothing. The bot stay connected but that's it. I can't see the messages, nothing.

I have tried many things for the past 4 hours.. including a lot of google search.. I can't figure out what is the problem.

Thanks

Code:

int status, sockfd, conn;
ssize_t receivedBytes;
char buffer[MAXDATASIZE];

int main()
{
    struct addrinfo hints;
    struct addrinfo *servinfo; //will point to the results

    //make sure the struct above is clear
    memset(&hints, 0, sizeof hints);

    //setup hints
    hints.ai_family = AF_UNSPEC; // don't care IPv4 or IPv6
    hints.ai_socktype = SOCK_STREAM; // TCP stream sockets

    //Setup the structs if error print why
    status = getaddrinfo(server.c_str(),port.c_str(),&hints,&servinfo);

    //si getaddrinfo retourne pas 0 il y a un erreur
    if (status != 0)
    {
        cout << "getaddrinfo:" << gai_strerror(status) << endl;
    }

    //setup the socket
    sockfd = socket(servinfo->ai_family,servinfo->ai_socktype,servinfo->ai_protocol);

    //si le socket retourne -1 il y a un erreur
    if (sockfd == -1)
    {
        perror("client: socket error");
    }

    //Connection to the socket
    conn = connect(sockfd, servinfo->ai_addr, servinfo->ai_addrlen);

    // si la connection retourne -1 il y a une erreur
    if (conn == -1)
    {
        close (sockfd);
        perror("client: error connecting to the socket");
    }

    if (servinfo == NULL) {
        cout << "Failed to connect" << endl;
    }

    //cout << "#### DEBUG 01 ####" << endl;

    addpredefinedaliases(); //ajoute les alias par default

    //creer un loop infini (1) qui va lire les réponses du serveur tout la duré d'éxécution du prog.
    //s'assure que nous somme connecté. voir env. L238
    int count = 0;
    while (1){

        if(count != 1){
            //after 3 message du server send data to server (as per IRC protacol)
            sendData("USER "+username);
            sendData("NICK "+nick);

            count++;
        }

        //grace au loop infini, reste Ã* l'écoute des réponses du serveur
        //les réponses sont stocké dans buffer
        receivedBytes = recv(sockfd, buffer, MAXDATASIZE-1,0);

        //break if connection closed
        if (receivedBytes == 0)
        {
            cout << "----------------------CONNECTION CLOSED BY REMOTE---------------------------"<< endl;
            cout << timeNow() << endl;

            break;
        }else if(receivedBytes == -1){
            cout << "----------------------ERROR---------------------------"<< endl;
            cout << timeNow() << endl;

            break;
        }else{
            cout << receivedBytes << " :" << buffer; //affiche le buffer
        }

        //répond au ping si envoyé. Protocol IRC
        if (recvPing(buffer, "PING"))
        {
            sendPong(buffer);
        }

        string str_buf = buffer;
        //join le channel lorsque connecté
        if ((str_buf.find("376") != string::npos) && settings.autoJoin_onConnect){
            sendData("JOIN "+channel+" "+channelpwd);
        }

        //traite les messages recu du server
        //msgHandler(buffer);

        //clean buffer et le remet Ã* 0 Ã* chaque nouveau message du server. Sinon lorsque buffer = MAXDATASIZE ça renvoie plus rien car plein.
        bzero(buffer, sizeof(buffer));
    }
    //libere la mémoire de la structure pointeur *servinfo
    freeaddrinfo(servinfo);

    return 0;
