putting a check if a process exited

[johri21]

Under restart the init script is stopping the process and starting it again.
When stopping it does not wait and issues a SIGTERM to the process, this causes trouble when the server was not able to shutdown within a minuscule time and a start is issued.
The same thing we encountered in production where under restart the server was not able to stop and a start was issued.
Logs:

Fix:
Waiting for the process to end and then issuing Kill if it does not stop.
