How to Kill zombie process with same Parent Process ID
#ps -el | grep 'Z'
Above command displays all the zombie process in the server. If all the PPID's are same you can kill by using our well known command "Kill"
#kill -9 <PPID>
Suppose if the PPID's are different follow the below steps.
# kill -9 `ps -A -ostat,ppid,pid,cmd | grep -e '^[Zz]' | awk '{print $2}'`
Explantion of the above command
ps -A -ostat,ppid,pid,cmd
this part of command displays the output with only the processes Status,Parent PID,PID and command which runs the processes
Example:
STAT PPID PID CMD
Ss 8782 8784 -bash
grep -e '^[Zz]
this part piped with the command to pullout the Zombie process from the list
awk '{print $2}
this is to pull out the PPID from the result displayed.
Atlast the command forms like below and kills all the zombie process
# kill -9 `ps -A -ostat,ppid,pid,cmd | grep -e '^[Zz]' | awk '{print $2}'`
This is how to kill the zombie process.
