PM2 stopped apps - autorestart does not work?

[michaelmms]

Hello,
I have some data collector nodejs apps controlled by PM2. After some hours they are displayed as stopped in “pm2 list”

Here it some info from “pm2 show”

I want pm2 to restart the scirpt always if it crashes…
May be there is some setting that prevents restarts?

thx
