tmshutdown -w/-k may be used to speed up the shutdown process. Most of the time a SIGTERM is sent by tmshutdown -w but depending on the delay specified a SIGKILL may be issued. The SIGTERM signal is trappable is the Tuxedo libraries contain a corresponding signal handler to force a process receiving the SIGTERM signal to terminate properly. As opposed to SIGTERM, SIGKILL is not trappable and may cause the process to terminate is any portion of code, even critical one. Thus sending a SIGKILL may cause the process to terminate while updating the BB with potential damage to the BB structure.
