Just digging around I find one value ever-growing in vmstat -z and being 
by far the biggest "USED" value:

virgin# while ( 1 )
while? echo -n `date`: ; vmstat -z | fgrep NAMEI | sed 's/  */ /g'
while? sleep 10
while? end

I'll recheck that in more busy times again.

Philip:

Are you using:

- another file system (like UFS/FFS for the system or similar?)
- ZFS snapshots
- ZFS send

on the system?

Can you also see the NAMEI growth?
