My system is taking 67% of the memory and I am experiencing High Swap utilization issue, I want to check which process is taking this much memory and eating swap memory

I also used the command

[/HTML]
root@sssdpmds01$ swap -s
total: 33396592k bytes allocated + 6862496k reserved = 40259088k used, 2185832k available
root@sssdpmds01$ swap -l
swapfile dev swaplo blocks free
/dev/vx/dsk/bootdg/swapvol 308,29001 16 33458672 19543392

I'd take a wild guess that it's ogw's multiple >2G java process that are using the memory.

You can limit this by setting the -Xmx flag, however if they are servlet or application servers (Tomcat, Websphere, etc...) then you will be forcing class disposal which may slow the individual process down (though not as much as swapping out does). Perhaps you need to re-define your sizing requirements?

Code:
ps -elfy | head -1; ps -elfy | grep -v SZ | sort -nrk 9 | head

Output will be sorted by SZ i.e Total virtual memory consumption (Real+Swap in KB)
the -y switch enables RSS (Residential size i.e real memory consumption in KB) so that you can make estimation of how much swap memory is being used by process (i.e SZ - RSS).
