Econn重置并在与elasticsearch连接的node.js客户端中将内存堆出空间

我有一个代码可以解析70个日志文件（每个文件大约15MB）。我从日志中提取特定字段，并向elasticsearch发送批量请求。下面是代码

//looks for all the files with .log extension

glob(__dirname + "/../logs/*.log", function (er, files) {
for (var i = 0; i < files.length; i++) {

    lr = new LineByLineReader(files[i]);
    lr.on('error', function (err) {
        console.error(err.stack);
    });

//each line of the file is taken and certain fields are taken from it and pushed into an array
    lr.on('line', function (line) {
        arr = line.replace(/['"]+/g, '').split(" ");
        var jsonArg1 = new Object();
        var temparr = arr[13].split("?");
        jsonArg1.url = temparr[0];
        jsonArg1.method = arr[12];
        pluginArrayArg.push(jsonArg1);
    });
//once the entire file is parsed, the array is pushed into elasticsearch bulk api

    lr.on('end', function () {
        // All lines are read, file is closed now.
        data = (function () {
            var x = '';
            for (var i = 0; i < pluginArrayArg.length; i++) {
                x = x + '{ "index" :  { "_index" : "nodeclient" , "_type": "logs"} }\n' + '{"method" : "' + pluginArrayArg[i].method + '", "url" : "' + pluginArrayArg[i].url + '"}\n';
            }
            return x;
        })();

        client.bulk({
            body: [
                    data
                    ]
        }, function (err, resp) {
            if (err) {
                console.log(err);
            }
            console.log(resp);
            //console.log(JSON.stringify(resp));
        });
    });
    }
});

我尝试过在命令行中增加堆空间，如下所示，但仍然不起作用

节点--max_old_space_size=4096 server.js

分别搜索这些错误，人们谈论增加maxSockets和重用池连接。我不知道如何对我的代码进行这些更改

我应该如何着手解决这些错误？这两个错误是否相关？

我刚刚使用自定义批量插入脚本批处理了许多25-40mb的文件，收到了EconReset错误

我将虚拟盒安装上的内存从4mb增加到8mb左右，我不再有这个问题
