For their quick and clearly answer.
All of them tell us that I should use "lazy swap" instead of preallocated
mod.
by using a command: /sbin/sysconfig -q vm vm_swap_eager to show the value
and by edit /etc/sysconfigtab
vm:
swapdevice = /dev/disk/dsk0b
vm-swap-eager = 0
set vm-swap-eager = 0 instead of 1.
A very useful command also:
fuser -c /dev/disk/dsk0b
fuser -c /dev/disk/dsk2b
to show process using swap.
Thanks again for all of them.

Dear Managers,
We have a Alpha 4000 with Tru64 V 5.1A, patched recently with
t64v51ab21as0004-20030206.tar, but we noticed that the server has a swapon
space below 10 % free shown at console,see below:
But there are no special process turn on, this message come even after a
reboot. There are nothing special either at crontab. Is there a method to
determine which process take all this swap space?
Any help would be appreciate, Thanks in advanced.
bash-2.04# swapon -s

Swap partition /dev/disk/dsk2b:
Allocated space: 76781 pages (599MB)
