When sending SIGKILL to Tuxedo processes, if Tuxedo is running critical section of shared memory(for example, changing the bulletin board tables under lock or unlocking the bulletin board memory area),
bulletin board (also known as BB) corruption may occur and cause unexpected problem. (for example - hang with LIBTUX_CAT:5005, crash and service table corruption)
Tuxedo is sending an operating system SIGKILL to application processes in the following situations (so it should be done carefully):
Service timeout (it reaches to the SVCTIMEOUT configured in the Tuxedo ubbconfig configuration file)
