Question

我有一个nodejs应用程序，我将其用作CouchDB实例的update_notification处理程序的外部进程。
nodejs应用程序负责从一些标准DB复制到新创建的DB。复制以某种方式工作，但nodejs应用程序被任意破坏。

这是应用程序监听通知处理程序的代码

var stdin = process.openStdin();


stdin.setEncoding('utf8');


stdin.on('data', function(d) {
    // Parsen des Ergebnis
    if (d !== null) {
        parsedData.push(JSON.parse(d));
    }
});

这是代码来自数组parsedData

的代码

var checker = function() {
    for (var index in parsedData) {
        var parsed = parsedData[index];
        if (parsed.type === "created" && parsed.db !== "design" && parsed.db !== "custom") {
            // start replication
        }
    }

    parsedData = [];

    setTimeout(checker, 1000);
};

这是错误日志

当我在不同的网站上阅读时，外部进程必须处于无限循环中。但我不确定我的设置是否有点无限？

CouchDB update_notification，nodejs
