Process zombie problem in container

docker

(botbot) #1

Run the docker image.
When you raise a container, you run one daemon server.
The daemon server does not fork and only a few threads are created
If you stop the daemon server in bash, it goes through the normal shutdown phase and runs to exit (0).
But since then, the process becomes zombie.
I wonder why this is the problem. I would also like to find a solution.
