Doing a "kill -9" should be reserved for a last resort. Doing a "kill -9" as the first thing you try is a terrible idea. In the case of fbackup, it is a disaster. Do a "kill -15 pid. Or just a "kill pid". The author of the kill program made -15 the default for a reason. In the case of fbackup, it will catch the -15 and go though a graceful shutdown procedure. fbackup is managing a suite of other processes and these must be shutdown first. And ipc's must be released. Especially a rather large shared memory segment. If you kill fbackup with a -9 that shared memory segment will remain allocated. It can be manually removed with ipcs/ipcrm but if you remove the wrong segment you will screw something else up. A reboot will be the safest way to recover.

killall

killall(1M)						  System Administration Commands					       killall(1M)

NAME

       killall - kill all active processes

SYNOPSIS

       /usr/sbin/killall [signal]

DESCRIPTION

       killall is used by shutdown(1M) to kill all active processes not directly related to the shutdown procedure.

       killall terminates all processes with open files so that the mounted file systems will be unbusied and can be unmounted.

       killall sends signal (see kill(1)) to the active processes. If no signal is specified, a default of 15 is used.

       The killall command can be run only by the super-user.
