I am using Linux OS and using multiprocessing in my application.

The child process execution get completed but the processes are not terminating.


childprocess = "/opt/oracle.ahf/exachk/exachk -silentforce -showpass -dball -nocvu -autorun_id DEFAULT -localonly -sudo_remoterun 0"

session = subprocess.Popen(childprocess, shell = True)
session.communicate()  

From the log I can see execution of childprocess scripts(exachk and exachk.py) is completed successfully but the process remains alive forever. Also the parent process from where I am using subprocess.Popen that also remains alive.

# ps -ef|grep exachk

Please help!

This is probably not a python bug. But if you can demonstrate it without needing to install the Oracle software, we can take a look at it. You've also not explained how you're using multiprocessing. We need an complete, short, working example program to determine if it's a python bug.

I suggest you ask this question on Stack Overflow.

Also, I'd suggest subprocess.run instead of .communicate, if you can.

For future reference, here are some good guidelines for submitting bug reports and asking for help to debug your code:

I'm going to close this. If you can reproduce it with a smaller program that we can test, please attach the information and re-open this issue.
