A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

  7. No low-effort posts. This is subjective and will largely be determined by the community member reports.

=> 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 ?

Zombies that stick around for more than a few seconds indicate a signal problem in the parent process, where its init is stuck in the "wait" state, so the entry remains in the PID table.

It could be harmless, but it could become a problem if you need the resources. Curl shouldn't be doing this on its own.

That's the thing. None of them are consuming resources. I guess I should just ignore them, but it irritates me when I start my server, to see zombie processes. Makes me think something is askew.

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.
