Graceful Exit

We are a pm2 and keymetrics user.

We handle graceful exit of child processes on SIGINT. However, the process is killed even before the graceful exit function is called. This is because after you issue a process.kill(pid, 'SIGINT') call, you immediately kill the process tree.

Cluster or fork?

Cluster.

Ok, the graceful exit handler on our SIGINT and SIGTERM had to be synchronous functions. We used node fibers in order to execute all our cleanup functions before PM2 kills the process.

Can you provide a code sample?

[benjsicam]

I think this is now handled by the kill_timeout option.

The issue was that we called disconnect() on processes in cluster, throwing all the exit logic. Now it has been fixed:

$ npm install pm2@next -g
$ pm2 update

Patch available on pm2@2.1.4 (main):

$ npm install pm2 -g
$ pm2 update
