acua_updated [-a] [-d] [-l x]

acua_updated is a daemon that monitors system usage, kicks users off as needed, and performs other important tasks such as book-keeping. You should have it started from one of your system's init scripts (e.g. /etc/rc.d/rc.sysinit). acua_updated should be running at all times.  I suggest running acua_updated from /etc/inittab because if acua_updated has a problem and dies, the init process will start it again immediately.  Without acua_updated your accounting and a few other things won't work.

Example /etc/inittab entry:

au:2345:respawn:/usr/sbin/acua_updated -d

The -d option is needed to stop init continually re-spawning the acua_updated daemon, which could also result in some other nasty stuff happening (not to mention eventually filling up your RAM, process table, and console with acua_updated programs or related error messages).  In the event that acua_updated has a major problem and keeps dying as soon as init starts it, init will only try to re-spawn acua_updated once every 5 minutes.  Init clues on to a problem after it restarts the daemon about 8 times a second.
