I have this issue too, ntfy running in a Docker container keeps creating zombie processes.
I'm having this issue on two different servers:

Server2:

Just wanted to share that I ran into the same issue where htop and top were super slow because of these zombie processes. Turns out, turning off the health checks for Docker container did the trick for me.
