143(SIGTERM) / 130(SIGINT) instead of gracefully shutdown

Couldn’t use nodemon with concurrently or something similar, cause If I kill npm script with nodemon, then npm outputs have errors

• npx nodemon -v: 2.0.4
• node -v: v14.13.0
• Operating system/terminal environment: Arch Linux / kitty
• Command you ran: npm run start

Expected behaviour

Successful exit without ERR from npm

Actual behaviour

[1] sleep 2 exited with code 0
--> Sending SIGTERM to other processes..
[0] npm run nodemon exited with code SIGTERM
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! node@1.0.0 start: `npx concurrently -k "npm run nodemon" "sleep 2"`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the node@1.0.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/vlad/.npm/_logs/2020-10-10T14_28_36_051Z-debug.log

Steps to reproduce

Simple index.js:

let jobs = setInterval(() => {}, 1000)
process.on('SIGTERM', () => { jobs.unref() })

part of package.json:

"scripts": {
  "start": "npx concurrently -k \"npm run nodemon\" \"sleep 2\"",
  "nodemon": "npx nodemon ./index.js"
},
"devDependencies": {
  "concurrently": "^5.3.0",
  "nodemon": "^2.0.4"
}

Command to reproduce:

npm run start

I find the line which is the cause all of this, but i dont understand how can i workarund there

Done some experimenting tonight, nodemon@2.0.6 works seamlessly in this scenario, so rolling back to 2.0.6 for now

EDIT: Finally figured out the problem: the reason was me saving the file and killing the process at the same time ( happens because my editor saves file on focus change ). Sorry for flooding the thread with all this monologue, for some reason I was convinced the problem was in nodemon. Hopefully this information may be helpful to someone coming across the same issue =)

By the way I still get the same issue on Mac and Windows, and I am still not entirely sure what might be causing it though it gets a little less annoying after a while
