When a process dies, it becomes a zombie (almost dead) process whose only remaining purpose is to hold its death certificate (the exit status data returned by the wait family of system calls). When the death certificate has been collected, the process is finally removed from existence and from the systems’s process table. Zombie processes are marked as <defunct> in ps listings.
check ps aux | grep Z (getting list of all Z stat process with PID)
ps -o ppid <PID>
Successful output should include `parent PID with name`
Remove parent process
sudo kill -9 <PID or name>
