Paging space ? you have not posted any lsps -a or svmon from
throughout the day.

minfree is set to 240, so free pages will hover around 240. as soon
as the number of pages on the free list "free" drops below 240, the
scanner will kick in and start to look for candidate pages to free up
based on you maxperm and minperm settings.. as yours are low, then
numperm will probably always be above maxperm and you will be freeing
up file pages. This is when you will see numbers in the sc and fr
cols in vmstat, they stand for "memory pages scanned" and "memory
pages freed" .. the ratio of pages scanned to freed should be no more
that 4:1 and if higher this can indicate a memory contention issue.

so, back to your problem ? when you say paging space is used and not
freed ? i cannot see any evidence of this from your post and it looks
like you are confusing your terminology.

a quick calculation onb your AVM in vmstat shows
840084*4096=3440984064
3440984064/1024/1024=3281MB

So, how much memory does you system have ? it looks like 3GB from
"number of valid memory pages" output ?

and you require 3.2GB for you current workload, so you are going to be
doing some paging...

can you post some lsps and/or svmon to highlight your problem,
coudpled with vmstat 1 10 so i can tie it all together.

Cheers
