To find zombie processes on Linux:

#$ ps axo stat,ppid,pid,comm | grep -w defunct

Z 555 10242 Damn-Zombie < defunct >

First, you can try sending SIGCHLD signal to the zombie’s parent process using the kill command. Note that the above command gives you PPID (PID of parent process) of each zombie. In our example, PPID of the zombie is 250555.

#$ sudo kill -s SIGCHLD 555

If a zombie process still does not go away, you can kill the parent process (e.g., 250555) of the zombie.

#$ sudo kill -9 555

Once its parent process gets killed, the zombie will be adopted by the init process, which is a parent of all processes in Linux. The init process periodically calls wait()wait() to reap any zombie process.
