PM2 restarting keystonejs app repetitively

Question

I am using throng to cluster my keystonejs application, which seems to work fine but when I run

const throng = require("throng"),
      dotenv = require('dotenv');

(function usedotenv() {
    try {
        dotenv.config();
    }
    catch (e) {
        console.error(e);
    }
}());

throng({
  workers: process.env.WEB_CONCURRENCY || 1,
  grace: 4000,
  master() {
    console.log("Starting master node");
  },
  start(id) {
    console.log("Starting worker node "+id);
    require("./keystone");
  }
});

using pm2 start index

├──────────┼────┼─────────┼───────┼─────────┼─────────┼────────┼────────┼──────────┤

│ index    │ 11 │ cluster │ 12688 │ online  │ 23      │ 0s     │ 0 B    │ disabled │

The website works fine, but pm2 keeps restarting the apps because they're not using any memory: [PM2][WORKER] Process 0 restarted because it uses 0 memory and has ONLINE status

How do I keep pm2 from restarting my apps?

Answer 1

It looks like all of your processes are named the same "index". If you use

pm2 start 4

for example to start just the the one process does it stop the restarting of all process's?

I am just wondering if using the id to start it will allow it to identify just the single index, instead of all of the processes named index
