All they wanna do is east your brains. They're not unreasonable; I mean no one's gonna eat your eyes.

All they wanna do is eat your brains. We're at an impasse here. Maybe we should compromise.

Just open up the door. We'll all come inside, and eat your braaains!

If you open up the door, we'll all come inside and eat your brains!

The eye develop from brain tissue, so I wouldn't be so sure ...

@thingsiplay Stop their parent process and the zombie will go under init, then init will stop them.

That's what the video explains as well. Killing the parents will make init adopt and kill the children in the process. Problem is, that you might not want to stop / kill the parent process, depending on what you are doing. One should be very careful of doing so.

@thingsiplay Sorry you might right! In this case, I would debug the parent process and I would execute the wait() syscalls in its name, but it is hardly autimatizable and probably many people can not do that. Thanks the info!

peterhorvath@mastodon.de · 1 pts · 134d

@thingsiplay Yes, you are right. I think you could trace the parent, by a gdb, and then execute a wait() in its name.

who@feddit.org · 1 pts · 134d

To be clear, merely stopping the parent (SIGSTOP) will not do the job. You have to kill or otherwise end it.

You could just avoid killing processes

But where is the fun then? ;p On a more serous note, yes I agree. In most cases (probably all cases) there should be no need to get rid of zombie processes.
