How common is it to restart a NodeJS app?

I'm reading up on debates about what sort of restart programs people use with NodeJS. So for instance:

Some people like pm2, or Upstart, or Supervisord. 

Do you keep track of how often your app dies and is restarted? 

Of the die/restart cycle, how much is deliberate on your part (an Erlang style fail fast philosophy) versus how much is s a total surprise? 

For those of you who have apps that die often, what are the circumstances that cause it to die often?

Nope, not directly. But I do scan the logs from time to time to check if there's something unusual (including restarts).

I try to make any restart explicitly because of a new deploy. If my app is restarting on its own occasionally, it's a bug and I try to find it and fix it f I see it.

Usually bugs. An uncaught error in init, somewhere where I rely on a third-party site and it's module, but those break and I didn't try/catch this (because I didn't read the docs and saw that they might, or because they didn't document it at all), things like that.

HTH.

Thank you for that.
