How to display and kill zombie processes
To find if zombies exist
Use Linux Bulit-in "top" Command:
[root@amitmaheshwari.in ~]# top | grep Tasks
Tasks: 116 total, 1 running, 115 sleeping, 0 stopped, 0 zombie
Tasks: 116 total, 2 running, 114 sleeping, 0 stopped, 0 zombie
Tasks: 116 total, 1 running, 115 sleeping, 0 stopped, 0 zombie
Tasks: 116 total, 1 running, 115 sleeping, 0 stopped, 1 zombie
Check zombie Process by "ps" command:
[root@amitmaheshwari.in ~]# ps aux | awk '{ print $8 " " $2 }' | grep -w Z
example output: Z+ 7872
Kill the zombies
zombies are living dead, so the aren't always easy to kill.
Try executing: kill -9 PID
example: kill -9 7872
Hopefully it will work, else below command will check PPID (Parent Process ID and Kill it)
If you need a single line command that does the work you can try :
kill -HUP `ps -A -ostat,ppid | grep -e '^[Zz]' | awk '{print $2}'`
Great !! It works perfectly
