No, TRUNCATE was faster because there were no live records in the table.

How can such an infinite loop sneak into an index?
Hardware is from Sun, not a grocery store PC, so I don't suppose it to
be faulty.
Is there anything in the 8.0.x series that fixes this (or a similar) bug?
If I could point to something in the release notes, I may get them to
upgrade
and they may upgrade to a newer generation even.

Thanks.
