I am testing an APP under server enviroment:
Use of aaPanel or btPanel under ubuntu
Use of pm2 module
The app is running but restart on error
I am using custom error managment and log functions
I want pm2 just ignore all console.log(error) and errors ocurred in scripts located at node_modules and subfolder
Anny idea?
Thanks for your time and for any help
This is a example of some error log from pm2:
2021-03-12T01:52:51: PM2 log: App [MyApp] exited with code [0] via signal [SIGINT]
And this is a example of error in out log from pm2:

Aditional Notes:
The app run flawless under local enviroment
The pm2 is the problem some awfull bad config maybe!
I run and test the app using 'nodemon index.js' all ok
I run and test the app using 'node index.js' all ok
I run and test the app using 'npm start' all ok
I run npm update all ok
I run npm audit all ok
I'm running my node+react app on vps ubuntu machine using ssh.
I used nginx, pm2 for running my node js server, but when I check my logs it shows the following error:

My node js server file where I'm sending my react app in response:
app.use(express.static("IRS-Ecommerce/build"));
app.get("*", (req, res) => {
res.sendFile(path.join(__dirname, "IRS-Ecommerce", "build", "index.html"));
});
I've run npm build in my react app and build folder is present there, but it is showing this error that index.html is not there. I've checked the path, it is correct.
When I access public IP, my react app shows up which means it is working. But why am I seeing this error here?

I have an express nodejs server running in Ubuntu LTS with pm2. The server runs fine, but when I restart Ubuntu, the server is always rebooting.
I use an ecossystem.config like this:
module.exports = {
apps : [{
name: 'gTimeTracking',
script: 'index.js',
args: 'one two',
instances: 1,
autorestart: true,
watch: true,
max_memory_restart: '1G',
env: {
NODE_ENV: 'development'
},
env_production: {
NODE_ENV: 'production'
}
}]
};
I started the server with this command:
pm2 start ecosystem.config.js --env production
And with pm2 save
and I have this infinite error on Ubuntu reboot

Last time I had this problem I had to reinstall many times pm2 to relaunch the server, but now this method doesn't works and isn't an stable solution
What could be wrong?
I had to use pm2 cleardump for solve the problem with pm2 delete all and pm2 kill it didn't works for me. (I didn't have to change anything about the loggers path)
I recently pushed my node js and express server to the production.
After a few days of working on the production, I realized that sometimes with no reason my server stops responding for requests.
[31/Dec/2018:09:55:39 +0000] "GET /vehicles?user_lat=52.458876&user_lng=16.9006237 HTTP/1.1" - - ms
I was looking for an answer here but the only advice I found was to debug server and find out what is causing it crashes. Unfortunately, I am not able to find out where is the problem. I added listeners to the process to find unhandled promises rejection and uncaught exception but nothing was caught.
What I also found is when the server stops responding the CPU usage is
running high. Normally it takes 1-5%, but when it hangs it is around 20%.
The next strange thing for me is the output of pm2.log file. According to it, my server often restarts but I don't understand why.
pm2.log file:

On the production, I use pm2 to start my server.
Here is my server.js file:
var express = require('express'),
app = express(),
port = process.env.PORT || 3000;
const morgan = require('morgan');
const routes = require('./api/routes/main_routes');
const authMiddleware = require('./api/authorization/auth');
bodyParser = require('body-parser');
app.use(morgan(':remote-addr - :remote-user [:date[clf]] ":method :url
HTTP/:http-version" :status :response-time ms'))
app.use('/images', express.static(__dirname + '/markers'));
app.use('/cars', express.static(__dirname + '/cars'));
app.use('/video', express.static(__dirname + '/video'));
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
app.use(authMiddleware)
routes(app); //register the routes
app.use(function (err, req, res, next) {
res.status(err.status || 500);
res.send(err.message);
});
process.on('unhandledRejection', (reason, p) => {
console.log("Unhandled Rejection at: Promise ", p, " reason: ",
reason);
});
process.on('uncaughtException', function (exception) {
console.log(exception);
});
app.listen(port);
console.log('server started on:' + port);

I am experiencing problems reloading the application using the ecosystem.config.js file. When the application is started for the first time, it starts correctly, but when I refresh/reload the application using the ecosystem.config.js file, the application restarts several times causing an error.
My SO is Ubuntu Xenial, PM2 version is 3.2.2 and Node v10.13.0. The application uses the latest version from Express module (4.16.4).
If I reload the application with "pm2 reload app_name", this problem doesn't occur.
The ecosystem.config.js content:
module.exports = {
apps: [{
script: "./index.js",
instances: "max",
exec_mode: "cluster",
kill_timeout: "2000",
env: {
NODE_ENV: "development",
},
env_production: {
NODE_ENV: "production",
}
}]
}
When I run the first time:
$ pm2 reload ecosystem.config.js
[PM2][WARN] Applications index not running, starting...
[PM2] App [index] launched (2 instances)
node#ubuntu:/data/$ pm2 logs

When I reload the application by name (ex: pm2 reload app_name), the application contiue runnig, but I see some timeouts to kill process:
PM2 | 2018-11-23T14:01:02: PM2 log: pid=11296 msg=failed to kill - retrying in 100ms

PM2 | 2018-11-23T14:01:02: PM2 log: pid=11296 msg=process killed
But, even though timeouts occur the application is running.
When I execute "pm2 reload ecosystem.config.js", the PM2 restart the application several times and one instance fail:
0|index | at Module.load (internal/modules/cjs/loader.js:598:32)
0|index | at tryModuleLoad (internal/modules/cjs/loader.js:537:12)

0|index | at Object. (/usr/lib/node_modules/pm2/lib/ProcessContainerFork.js:48:21)
0|index | Error: listen EADDRINUSE :::3001
I believe the problem is related to some timeout to properly terminate the http connection of the Express module, but I'm still investigating this.
It has been fixed on the lastest PM2 version, please update:
npm install pm2#latest -g
pm2 update
Make sure you pm2 delete all and then start back your application again, it will work then when doing reload or restart
