An exception occurred while "service" stop

Write the management script of the background process, when using service Deamon-name stop, the following prompt appears:
/sbin/service:line 66:23299 Terminated env-i lang= "$LANG" path= "$PATH" term= "$TERM" "${servicedir}/${serv ICE} "${options}

The reasons are:
I set the name of the management script to be the same as the background process name, i.e.:

Background process name: Deamon-name,
Script Name:/etc/init.d/deamon-name

There is a sentence in the script:
Killall Deamon-name
Execute service deamon-name stop, which is intended to call the Deamon-name script, end the background process deamon-name, and the result even the "service Deamon-name Stop" process is also ended.

Workaround:
Sets a different name for the background process and script.
