=> 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 <defunct>. 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 <defunct>?
No idea about your specific case, but in the past when I’ve had frequent zombies it’s been due to some blocking network process; typically NFS mounts.
They don’t use any resources, but I agree they’re annoying and could indicate some underlying issue.
I would check for issues with I/O and network access, especially anything that happens at kernel level. Look for anything suspicious in dmesg.
I’ll check that out.
