We have a NW6.5 sp2 server. Purgeable space shows a negative number. In
the past we can do a purge all from the root to clean them up. It doesn't
work anymore. We tried using Filer, Remote Manager etc but it just won't
purge. As a result we can't use salvage as well. As there is nothing to
be salvaged since the purgeable space are not working right.

Where should I look and is there anything we can do to resolve this?
