我正在MEAN Stack中开发一个Web应用程序，不幸的是遇到了这个错误。

我在MongoDb中运行批处理查询，但是在执行批处理查询时我收到此错误，
{ name: 'MongoError', message: 'connection 5 to localhost:27017 timed out' } undefined
同步运行这3个批处理查询，批处理查询的代码是：
var User_Earning_Buckets = db.collection('userearningbuckets');
var Users = db.collection('users');
var Admin_Account_Details = db.collection('admin_account_details');
var User_Earning_Buckets_Batch = User_Earning_Buckets.initializeOrderedBulkOp();
var Users_Batch = Users.initializeOrderedBulkOp();
var Admin_Account_Details_Batch = Admin_Account_Details.initializeOrderedBulkOp();
function(...) //running queries for batch query
Users_Batch.execute(function(err,resUsers){
Admin_Account_Details_Batch.execute(function(err,resAdmin){
User_Earning_Buckets_Batch.execute(function(err,resUserEarning){
console.log("Batch Execution Completed")
});
});
});
每批次的查询数量约为。 10,000个查询。
db连接字符串是：
var options = {server: {socketOptions: {connectTimeoutMS: 30000,keepAlive:3000}},replSet: {},mongos: {},auto_reconnect: true,poolSize: 500};
var url = "mongodb://admin:admin@localhost:27017/testDb"
MongoClient.connect(url,options, function(err,db) {})
日志文件中的最后一行是：
