The awslogs agent spawns the zombie process again

I am running awslogs agent on ubuntu 16.

when i start the awslogs agent two processes were created.

$ sudo systemctl start awslogs
root     25973     1  0 Feb13 ?        00:00:00 /bin/sh /var/awslogs/bin/awslogs-agent-launcher.sh --start --background --pidfile --user awslogs --chuid awslogs &
root     25976 25973  0 Feb13 ?        02:16:01 /var/awslogs/bin/python /var/awslogs/bin/aws logs push --config-file /var/awslogs/etc/awslogs.conf --additional-configs-dir /var/awslogs/etc/config

      

        
        
        
      

    

and when i stop awslogs only one process is killed. another process is still alive.

$ sudo systemctl stop awslogs
root     25976 25973  0 Feb13 ?        02:16:01 /var/awslogs/bin/python /var/awslogs/bin/aws logs push --config-file /var/awslogs/etc/awslogs.conf --additional-configs-dir /var/awslogs/etc/config

      

        
        
        
      

    

when I start the awslogs agent again, two processes are created. therefore, the entire count of the process is 3.
