I am using pm2 version 4.2.3

When I run this mand: pm2 start node launchers/engine_launcher.js --name "engine", it starts the following:

id  │ name                           │ namespace   │ version │ mode    │ pid
------------------------------------------------------------------------------
12  │ engine                         │ default     │ 0.34.0  │ fork    │ 893
13  │ engine                         │ default     │ 1.0.0   │ fork    │ 8946

I want only one process to be started. If I pm2 delete engine, both go away.

launchers/engine_launcher.js is a regular javascript script.

What causes this problem? How can I start only one version of my script?

This doesn't happen for other scripts, only this one.

• javascript
• node.js
• pm2

Instead of start node app.js use just start app.js.

pm2 delete 12 is one way to do it.
