from the man page: Managing the Jail Normal machine shutdown commands, such as halt(8), reboot(8), and shutdown(8), cannot be used successfully within the jail. To kill all processes in a jail, you may log into the jail and, as root, use one of the following commands, depending on what you want to accomplish: kill -TERM -1 kill -KILL -1 Last I read, a process couldn't trap SIGKILL to do anything with it, wheres SIGTERM is trappable, so a proper shutdown of the process can be accomplished, whereas -KILL just blows it out of the water ...
