The waitpid() request issued by /usr/sbin/init to wait for the shell with pathname <shell-pathname> to execute the initialization script returned control to /usr/sbin/init at <date/time> because the shell was terminated by a signal with signal number <sig>.
/usr/sbin/init exits with status 11 (hexadecimal). The system continues.
Investigate why the shell received the terminating signal.
