Re: find command causes mem problems
UNIX95=1 ps -e -o vsz,pid,ppid,args | sort -rn | head -20
This will show the largest processes. Run it several times to see if some are growing larger.

Re: find command causes mem problems
What's chicken and what's egg?
That is, are you monitoring performance before starting the find() or is your find() taking longer than you expected and *then* you see performance issues?
How are you measuring swapping? What values do you see when find() isn't running and what values do you see when it is. Page-in activity is immaterial. What matters is the page-out values as reported by 'vmstat'.
If you post the *exact* find() command (in full) that you are using, we might be able to provide some better commentary.
Too, give us an idea of the number (if only in orders of magnitude) of items that find() traverses. That is, are you only searching a directory like '/etc' or are you searching something like '/var' on a heavily patched system?
Regards!
