=> There are 90 zombie processes.

On one of my Homelab servers running Ubuntu Jammy, I always seem to get zombie processes. A quick check with ps -eo pid,ppid,stat,cmd | grep -w Z shows them all . It just bugs me. I shut down the server in the most nicest of ways I know how with sudo shutdown -h now but I always get zombie processes shown on start up.

Am I missing something? Do these show up on your servers? How do you deal with them besides just ignoring them if they are ?

Zombie processes do not use resources, well, a little, it's basically an entry describing how it exited.

The parent process is the thing keeping the zombie entry open. Killing it's parent should work if they bother you.

    Agreed, but a very poorly-written program having a hanging memory or disk write, or a file lock could become a problem, especially if hundreds or thousands of zombies are waiting for something.
