具有快速停止响应请求的 Nodejs 在工作一段时间后停止响应请求

Question

我的服务器正在运行，但工作一段时间后它停止响应请求，继续尝试加载页面，因为我无法建立连接。

我的应用.js

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var oracledb = require('oracledb');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var session = require('express-session');
var multer = require('multer');
var fileUpload = require('express-fileupload');
var sessionStore;
var app = express();
var oracleDbStore = require('express-oracle-session')(session);
var connect = require(path.join(__dirname, 'connection', 'conn'))(2);
oracledb.createPool(connect, function(err, pool) {
      if (err) {
        console.error("createPool() error: " + err.message);
        return;
            }
            pool.getConnection(function(err, connection) {
                if (err) {
                    handleError(response, "getConnection() error", err);
                    return;
                }
                var diffopt = {externalAuth: true,
                            checkExpirationInterval: 900000,
                            expiration: 86400000,
                            createDatabaseTable: true,
                            connectionLimit: 1,
                            schema: {
                                tableName: 'sessions',
                                columnNames: {
                                    session_id: 'session_id',
                                    expires: 'expires',
                                    data: 'data'
                                }
                            }};
                var options = Object.assign({},connect,diffopt);
                sessionStore = new oracleDbStore(options, connection);
            });
        });
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'twig');
// uncomment after placing your favicon in /public
app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(fileUpload());
app.use(cookieParser());
app.use('/files',express.static(path.join(__dirname, 'public')));
app.use('/archivos',express.static(path.join(__dirname, 'archivos')));
app.set('trust proxy', 1);
app.use(session({
    secret: "work",
    name: 'sessionId',
    store:sessionStore,
    resave: false,
    saveUninitialized: false
}));
var links = require('./links');
for(var i=0;i<links.length;i++){
    app.use(links[i].route, require(links[i].direction));
}
app.get('*',function(req,res){
    res.redirect('/');
});
app.get('/', function(req, res){
  res.sendFile(path.join(__dirname, 'views/index.twig'));
});
// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});
// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};
  // render the error page
  res.status(err.status || 500);
  res.render('error');
});
module.exports = app;

服务器停止响应但仍收到请求时的日志。它不能加载任何视图或静态文件。

最后，我需要重新启动服务器才能使其再次工作。

感谢您的回复，问题是 oracledb 池，当它过期时它会挂起服务器。我将其更改为快速文件存储，现在它可以正常工作。

app.use(session({
    store: new FileStore(options),
    secret: "work",
    name: 'sessionId',
    resave: true,
    saveUninitialized: false
}));
