Question

我在我的风帆应用程序中有这个控制器代码：

let userId = req.body.userId;
User.findOne({ id: userId })
  .then((user) => {
    console.log('User found:', user);
    return res.ok('It worked!');
  }).catch((err) => {
    sails.log.error('indexes - error', err);
    return res.badRequest(err);
  });

当我启动我的服务器时，它可以工作，但是经过一段时间（约5分钟）它停止工作，我最终得到以下错误信息：

web_1  | Sending 400 ("Bad Request") response: 
web_1  |  Error (E_UNKNOWN) :: Encountered an unexpected error
web_1  | MongoError: server 13.81.244.244:27017 received an error {"name":"MongoError","message":"read ETIMEDOUT"}

此时数据库仍处于运行状态，查看日志，这一切似乎都很好：

2017-03-23T16:45:51.664+0000 I NETWORK  [thread1] connection accepted from 13.81.243.59:51558 #7811 (39 connections now open)
2017-03-23T16:45:51.664+0000 I NETWORK  [conn7811] received client metadata from 13.81.253.59:51558 conn7811: { driver: { name: "nodejs", version: "2.2.25" }, os: { type: "Linux", name: "linux", architecture: "x64", version: "4.4.0-62-generic" }, platform: "Node.js v4.7.3, LE, mongodb-core: 2.1.9" }
2017-03-23T16:45:51.723+0000 I ACCESS   [conn7811] Successfully authenticated as principal username on dbname

我的connections.js挂钩看起来像这样：

module.exports.connections = {
  sailsmongo: {
    adapter   : 'sails-mongo',
    host      : process.env.MONGODB_HOST,
    port      : 27017,
    user      : process.env.MONGODB_USERNAME,
    password  : process.env.MONGODB_PASSWORD,
    database  : process.env.MONGODB_DBNAME
  },
}

和package.json：

"sails": "~0.12.4",
"sails-mongo": "^0.12.1",

备注：

在未经证实的可能的不当行为来源中，我看到：

该应用已停靠
我的查询需要相当长的时间（约1/2分钟）并调用多个子进程，所以我怀疑有一些内存泄漏，尽管这仍未经证实！

对此有什么想法吗？

编辑：

经过一番挖掘后，我有一个印象，看着sails / waterline的DB日志在每个查询上打开一个新连接，同时应该插入一次并保持活动状态。这可能是问题的原因。

由此，我决定在Mongoose尝试Mongoose和宾果游戏，它就像一个魅力。

我猜这是发生了Sails / Waterline的错误，虽然我不清楚如何正确地重现这个错误。

无论如何，我现在正将我的应用程序从Waterline移到Mongoose。
