Question

我正在运行带有socket.io的nodejs服务器，用于客户端之间的实时通信，并且突然所有客户端（iPad）都断开连接。除了运行＆＃34;仪表板＆＃34;在Mac上。服务器没有崩溃，之后客户端没有重新连接。我不得不重新启动节点服务器，然后重新连接所有节点服务器。有没有人遇到这样的事情？如果重要的话，我可以提供代码。客户端正在运行WebApp。服务器：

`io.on('connection', function(socket){
var id = socket.id;
writeTo("User Connected! Group: "+socket.id);

socket.emit('responseID' , { socketId : id } );

socket.on( 'registerGroup' , function(data){
    var group;
    if(data.groupId!=''){
        group = data.groupId;
        socket.emit('registerIDRes' , { groupId : group } );
    }else{
        groupCount ++;
        group = groupCount;
        socket.emit('registerIDRes' , { groupId : group } );
    }

    groups[socket.id] = group;
    $("#log_wrapper").prepend('<div class="alert alert-success" role="alert">Group Register: '+group+'</div>');
    writeTo("Group Register: "+group);
