随机获取RangeError：通过 Socket.IO 房间概念将数据发送到连接的客户端时超出了最大调用堆栈大小。经过几个论坛，它说数据对象可能有自引用数组 Node.js + Socket.io 超过最大调用堆栈大小可能会发生此异常，但在我的代码中，我在纯字符串数据和数据对象中都出现异常还。

以下是示例代码片段

发送纯文本

socket.emit('STATUS','OK');

发送对象数据

var clients = socketio.sockets.adapter.rooms['ROOMID'];

if(clients != undefined && clients != null)
{
    console.log('Sending data to client');
    socketio.sockets.in('ROOMID').emit('DATA', data);
}
