Question

在nginx和pm2下运行的服务器。它使用mongoose来连接到MongoDB Atlas。前端使用axios从服务器获取数据。

服务器运行了很长时间（几天）后，我的网站无法从MongoDB Atlas获取数据。显示500个服务器错误。

服务器仍在运行，显示用户界面，但无法获取数据。重新启动整个服务器后，它就可以正常工作。

谁遇到过这种情况？

服务器

import * as React from 'react';
import {Suspense} from 'react';
import {View,Image,StyleSheet,Text,Button} from 'react-native';
import NavigationService from './NavigationService';
import MenuLogic  from './LoadMenuLogic';
import { createAppContainer } from 'react-navigation';
import { createStackNavigator } from 'react-navigation-stack';


const TScreenReceive=({navigation})=>{
//  const Y = "./"+navigation.getParam('userName');
  const Comp = React.lazy( () => import('./Mosely'))

    return (
      <Suspense fallback={null}>
        <Comp />
      </Suspense>
    );
  }


  const TScreen=()=>{
    return(
      <TScreenReceive />
    )};



export {TScreen};

连接mongoDB

const express = require('express')
const connectDB = require('./config/db.js')
const cors = require('cors')
const path = require('path')

const app = express()

// Connect Database
connectDB()

// Init middleware
app.use(express.json())
app.use(cors())

// Define routes
app.use('/api/users', require('./routes/api/users'))
app.use('/api/auth', require('./routes/api/auth'))
app.use('/api/profile', require('./routes/api/profile'))
app.use('/api/posts', require('./routes/api/posts'))

// Serve the static assets in production
if (process.env.NODE_ENV === 'production') {
  // Set static folder
  app.use(express.static('client/build'))

  app.get('*', (req, res) => {
    res.sendFile(path.resolve(__dirname, 'client', 'build', 'index.html'))
  })
}

const PORT = process.env.PORT || 5000

app.listen(PORT, () => console.log(`Server started on port ${PORT}`))

长时间运行后，node.js服务器无法从mongoDB地图集获取数据
