Indy has an asynchronous cron ie one who does not need to keep the box
powered up 24 hours a day.  However updatedb by itself cannot produce
thse effects: it will slow your box due to the IO taking effect but
not in such proportions and it will not crash the box.

I would tend to think in netscape.  I have heard of such behaviour
with the version shipped in Indy 6.0 (who was the newets and greatest
at this time but netscape has been going from bad to worse).  I
presently use netscape 4.7
