pm2 reload ecosystem.config.js causing many restarts on application
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=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.
