Fred,

        That's otherwise known as 11i. No I would not consider it a concern, especially with 6GB of free space left. If that was 6KB that might be a different story.

We're running HP-UX B.11.11 U 9000/800, so is this a concern in our version?
Even at 99% capacity, I still have ~6GB free on the device. Thanks.
