启动时节点socket.io服务器崩溃 [英] Node socket.io server crash when starts

问题描述

我有一个socket.io服务器和一个客户端运行正常.每次服务器关闭时，客户端都会尝试每5秒重新连接一次.当服务器再次启动时，它们可以正常连接.

I have a socket.io server and a client runing correctly. Each time that the server is down, the client try to connect again each 5 seconds. When the server is up again they connect without problems.

但是问题出在我等待很长时间再重新启动服务器时，当服务器启动时，它崩溃，显示为:

But the problem comes when I wait long time before up the server again, when the server is up, it crashes showing :

info  - socket.io started
debug - client authorized
info  - handshake authorized DqN4t2YVP7NiqQi8zer9
debug - setting request GET /socket.io/1/websocket/DqN4t2YVP7NiqQi8zer9
debug - set heartbeat interval for client DqN4t2YVP7NiqQi8zer9
debug - client authorized for
debug - websocket writing 1::

buffer.js:287
  pool = new SlowBuffer(Buffer.poolSize);
         ^
RangeError: Maximum call stack size exceeded

客户端重新连接(未连接时每5秒执行一次):

Client reconnection (Executed each 5 seconds while is not connected):

function socket_connect() {
    if (!socket) {
        socket = io.connect('http://192.168.1.25:8088', { 'reconnect':false, 'connect timeout': 5000 });
    } else {
        socket.socket.connect();
    }
    socket.on("connect", function () {
        clearInterval(connect_interval);
        connect_interval = 0;
        socket.emit('player', { refresh_data:true });
    });
}

在服务器端，仅对于套接字实例，它会崩溃:

On server side, only with the socket instance, it crashes:

var io = require('socket.io').listen(8088);

我认为问题是:

服务器启动时，它每5秒恢复一次客户端发出的所有连接(15小时断开* 60 m * 60 s/5秒重新连接)，并且崩溃.

When the server goes up, it recive all the connections emited by the client each 5 seconds, (15 hours disconnected * 60 m * 60 s / 5 seconds reconnection) and it crashes.

我该怎么做才能关闭服务器尝试执行的连接?

What can i do to close the connections that the server try to do?

PS:如果我重新加载客户端，并且在服务器启动之后，它就可以工作

PS:If i reload the client, and after up the server, it works

推荐答案

我发现了问题...

每次调用函数socket_connect()时，都会创建一个"socket.on(" connect"...")函数.因此，当服务器启动时，将创建一个新的连接，但事件为"socket.on("connect"被触发多次...

Each time that the function socket_connect() is called, a "socket.on("connect" ..." function is created. So when the server turns up, a new connection is created, but the event "socket.on("connect" is fired multiple times...

解决方案是:

function socket_connect() {
    if (!socket) {
        socket = io.connect('http://192.168.1.25:8088', { 'reconnect':false, 'connect timeout': 5000 });
    } else {
        socket.socket.connect();
    }
}

socket.on("connect", function () {
        clearInterval(connect_interval);
        connect_interval = 0;
        socket.emit('player', { refresh_data:true });
    });
