Have you been able to verify that dm-8 is your paging device and that the paging rate is indeed high?
To find the top memory-consuming processes start "top" and check the "VIRT" column.

If I top than Sendmail ,vmxciad ,Patrol agent ,perl ,cmafcd etc all showing high in VIRT and Vmstat shows:

Where is your swap space:
/etc/fstab # (second column = "swap")
swapon -s
cat /proc/swaps
Map LVM logical devices:
lvdisplay|awk '/LV Name/{n=$3} /Block device/{d=$3; sub(".*:","dm-",d); print d,n;}'
Look for dm-8.

dmsetup info /dev/dm-8
should do the trick.
It can be an LVM volume, dm-raid set

yes dm-8 is a swap disk
dm-8 /dev/rootvg/lv_swap
cat /proc/swaps
Filename Type Size Used Priority
/dev/mapper/rootvg-lv_swap partition 8388600 3529772 -1
Now what should i increase it or what ?

You should examine the output of "top" (the "VIRT" column, remember?) for processes consuming excessive memory.
If there are no such processes or if you can't change their behaviour in regard to memory consumption you will have to reduce the load of that server (move some applications to another machine, for example) or buy more memory.

if that disk is a regular sata, it seems to be used at the maximum of it's capacities. the limitation is connected to the number of transactions as such disks usually cannot give a decent throughput once you reached 250-400 tps (the limit varies depending on the disk and OS)
what actually is your problem ? the OS run ? the specs of the machine ? it's use ? your goal ?

I think you're running too many "AutonomyContentServer" processes in relation to the main memory available on your machine - thus you're running into paging issues.
As I already told you before - either reduce the number of parallel processes, or, if you really need that many, consider purchasing more memory or moving parts of the load to another machine (if at all possible).
