PM2 leaves Zombie processes on host system

[lukaslindnermusic]

Hi 😊

Since installing immich-public-proxy on my server, I noticed that every once in a while, there are zombie processes.
I previously never had zombie processes on my system, so I checked what is causing the processes.

The processes are the wget cmd, apparently executed by dist/index.js, caused by pm2-runtime which is started by the docker container of immich-public-proxy.
I don't know, what exactly is causing the zombie processes, but here is an excerpt of my docker container log with the PM2 messages:

2025-02-08T00:12:38: PM2 log: Stopping app:index id:0
2025-02-08T00:12:38: PM2 error: Error: spawn ps ENOENT
2025-02-08T00:12:39: PM2 log: App [index:0] exited with code [0] via signal [SIGINT]
2025-02-08T00:12:39: PM2 log: pid=18 msg=process killed
2025-02-08T00:12:39: PM2 log: PM2 successfully stopped
2025-02-08T00:13:14: PM2 log: Launching in no daemon mode
2025-02-08T00:13:14: PM2 log: App [index:0] starting in -fork mode-
2025-02-08T00:13:14: PM2 log: App [index:0] online

Is this caused by something in the immich-public-proxy code or is it a bug in dependencies?

Thanks for your help 😊

Thanks for the info - I was thinking of removing PM2 anyway, as I'm not convinced it does anything useful. That should solve the issue after I do that.
