node.js套接字与aws-sdk挂起

Question

我在AWS S3中有超过50个csv文件（每个文件大约4MB）。 我想读取所有文件并推送数组，但我有＆＃34; socket挂断错误＆＃34;在程序中。 （当少于20个文件时，不会出现错误。）

如何解决此错误？

错误 -

  region: 'ap-northeast-1',
  hostname: 'hoge.s3-ap-northeast-1.amazonaws.com',

[每个版本] node.js v0.10.26 aws-sdk@2.0.17 csv@0.4.0

计划 -

var csv = require('csv'),
    aws = require('aws-sdk');
aws.config.region = 'ap-northeast-1';

var s3bucket = new aws.S3({ params: { Bucket: 'hoge' } });
s3bucket.listObjects({
  Bucket: 'hoge',
  Prefix: 'piyo'
}, function (err, listObjects) {
  if (err) { console.error(err) }
  listObjects.Contents.forEach(function (content) {
    if (content.Size > 0) {
      var key = content.Key;
      s3bucket.getObject({ Key: key }, function (err, data) {
        console.log(key);
        var newData = [];
        if (err) { console.error(err) }
        csv.parse(new Buffer(data.Body, 'base64').toString('utf8'), function (err, rawData) {
          var header = rawData[0], newCsvFileName;
          if (err) { console.error(err) }
          rawData.forEach(function (line, lineIndex) {
            line.forEach(function (col, colIndex) {
              if (colIndex != 0) {
                var time = line[0];
                newData.push([time, key, header[colIndex], col]);
              }
            });
          });
        });
      });
    }
  });
});

谢谢。
