왜 WSH는 죽지 않았을까요?
1. tmshutdown -k KILL 을 수행하면 tuxedo 엔진은 내부적으로 SIGKILL 시그널을 tuxedo의 AP Server 프로세스에게 전달됩니다.
2. 이러한 시그널을 받은 Server 프로세스들은 바로 종료됩니다.
3. 이때 WSH는 tuxedo 엔진 입장에서는 일종의 client이기 때문에 SIGKILL 시그널을 직접 받지 못하는 것입니다.
즉, 정상적인 종료인 경우에 WSL의 tpsvrdone 함수에서 WSH를 정리하는 단계가 있으나,
현재 SIGKILL시그널을 받아 갑자기 종료가 되므로 tpsvrdone 함수를 만나지 못하게 되어 WSH를 정리하지 못하고 종료되어 WSH 프로세스가 남는 것입니다.

TERM으로 tmshutdown을 하면
KILL과는 달리 tpsvrdone()을 수행하면서 process들이 종료가 되는데 이때 TERM을 받는 대상은 사용자 AP Server이고 BBL, DBBL, GWTDOMAIN, WSL들은 대상에서 제외됩니다.
TERM을 만든 이유가 사용자 AP Server 프로세스의 hang 현상을 제거하기 위해서 만들어진 것이기 때문에 이미 tuxedo 엔진에서 정의한 system server 프로세스들은 대상에서 제외된 것입니다.
