var/log/mongodb/mongod.log从node.js打开和关闭连接的无限循环

Inside /var/log/mongodb/mongod.log我有一个无限循环的打开和关闭连接。这使得mongod.log变得庞大，占用了磁盘空间。我也担心node.js应用程序中存在错误的代码。我在我的节点js应用程序中使用猫鼬和本地mongo驱动程序。我没有看到任何错误或例外。var/log/mongodb/mongod.log从node.js打开和关闭连接的无限循环

有没有人看过这个，以及可能的根本原因是什么？日志现在是11GB并且不断增长。

被调用一些特定的Node.js的代码经常

var MongoClient = require('mongodb').MongoClient; 
exports.logSession = function(payload) 
{ 
    MongoClient.connect(url, function (err, db) { 
     assert.equal(null, err); 
     insertSessionIntoTable(payload, db, function() { 
      db.close(); 
     }) 

    }) 

}; 

function insertSessionIntoTable(payload, db, callback) { 
db.collection(collectionName).insertOne(payload, function (err, result) { 
    assert.equal(err, null); 
    logger.verbose("Inserted a document into the collection."); 
    callback(); 
});

将您的node.js应用程序代码添加到问题中。 –

exports.logSession =函数（有效载荷） { MongoClient.connect（URL，函数（ERR，分贝）{ assert.equal（NULL，ERR）; insertSessionIntoTable（有效载荷，DB，功能（）{ db.close （）; }） }） }; –

请添加完整的连接代码更新问题。 –

您的代码将打开每个会话

exports.logSession = function(payload) 
{ 
    MongoClient.connect(url, function (err, db) { // for every session your code will open new connection 
     assert.equal(null, err); 
     insertSessionIntoTable(payload, db, function() { 
      db.close(); // here it will close it 
     }) 

    }) 
};

连接打开一次连接，并使用相同的连接做的所有操作。

var db; 
MongoClient.connect(url) 
    .then(function (dbInstance) { // <- db as first argument 
    db = dbInstance; 
    }) 
    .catch(function (err) {}) 

exports.logSession = function(payload) 
{ 
     insertSessionIntoTable(payload, db, function() { 
      // work done 
     }) 

    }) 
};

谢谢，这对我很有用。我实现它只是一次性使连接。所以我不需要关闭数据库，对吗？ –

@ tritium_3绝对正确。 –
