No, automatic reboots are possible and quite easy to setup - and you
don't need AutoRestart/iX to do them.

Way back on iX 6.0 there used to be many MANY networking bugs, such that
the system tables would fill up on a very busy system quickly (in our
case my Internet-connected box running a web server maxed out about
every 36 hours). A nasty workaround until HP fixed the bugs was a script
that ran hourly that checked the system tables, and if it found them
close to filling up, would stream a job that ran a simple program that
halted the box (after cleanly stopping all running jobs and warning all
users to log off). A simple PM program call (suddendeath I think) is all
that it took.

Meanwhile the system was configured to automatically restart when it
halted; a process that's documented in the FAQ at www.3k.com and merely
involves editing a file in pub.sys and making a syslog config change
IIRC. 

It worked (though a rather sad workaround) and though the problem is
long gone I still have my boxes configured to auto-restart.
