I'm unable to clean the zombie process , which is created by below command:

 log_file = "ui_console{}.log".format(index)
    cmd = "npm run test:chrome:{} &> {} & echo $!".format(index, log_file)
    print(f'run{index} :{cmd}')
    # This command will be run multiple time for each kvm instance in background, which is having bg pid and stor the stdout, stderr in log_file
    process = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, executable='/bin/bash')
    # Read the BG PID from the command's output

eaton@BLRTSL02562:/workspace/edge-linux-test-edgex-pytest$ ps -ef | grep 386819

eaton 386819 1 0 05:04 pts/2 00:00:01 [npm run test:ch] <defunct>

eaton 392598 21681 0 06:30 pts/3 00:00:00 grep --color=auto 386819

eaton@BLRTSL02562:/workspace/edge-linux-test-edgex-pytest$

how to clean the zombie PID ?

Tried below steps but no luck:

Find the Parent Process ID (PPID):
    ps -o ppid= -p <zombie_pid>
Send a Signal to the Parent Process
Send the SIGCHLD signal to the parent process to notify it to clean up the zombie process:
    sudo kill -SIGCHLD <parent_pid>
Replace <parent_pid> with the PPID obtained from the previous command.

Please suggest if there are any approach
