Question

在调试模式下，如果我的服务器在相当长的一段时间内（通常是整夜）处于运行状态，那么我来看看。

events.js:174
      throw er; // Unhandled 'error' event
      ^

Error [ERR_STREAM_WRITE_AFTER_END]: write after end

它没有指向代码中的任何地方，这可能是错误的根源。

Mongo连接功能：

function mongoConnect() {

    var options = {
        keepAlive: 1,
        connectTimeoutMS: 5000, // ms. default = 30000
        reconnectTries: 1000, // default = 30
        reconnectInterval: 5000, // ms. default = 1000
        family: 4, // force IPV4 to speed up connection

        // set this to remove a deprecation warning. See mongoose issue: 6890
        useCreateIndex: true,
        useNewUrlParser: true,
    };

    try {
        mainLogger.info(`connecting to: mongodb://${process.env.mongoServerIP}:${process.env.mongoServerPort}/${process.env.mongoDatabaseName}`);
        mongoose.connect(`mongodb://${process.env.mongoServerIP}:${process.env.mongoServerPort}/${process.env.mongoDatabaseName}`, options);
    } catch (error) {
        mainLogger.error(`Error while connecting to mongo DB: ${error}`);
    }

    return mongoose.connection;
}

Mongo事件处理程序：

mongoConnect()
    .on("error", function (...messages) {

        mainLogger.error(`Mongo connection error: ${JSON.stringify(messages)}`);

        fatalError.error = true;
        fatalError.mongoConnectError = true;
        fatalError.mongoErrorMessages = messages;

        mainLogger.error(messages);

        listen();

    })
    .on("disconnected", mongoConnect())
    .once("open", function (...messages) {

        mainLogger.info("Mongo connected successfully.");

        fatalError.error = false;
        fatalError.mongoConnectError = false;
        fatalError.mongoErrorMessages = messages;

        if (messages.length > 0)
            mainLogger.info(messages);

        listen();
    });

任何人都可以提供问题根源的任何指示吗？
