top(1)
sort by size and/or res

ps(1)
maybe:
	ps -ax -o vsz,rss,rsz,tsiz,pid,comm | sort -n

Maybe you can see what process(es) are growing?

Maybe you aren't actually losing memory, but NetBSD is doing good job and 
using your memory.

See output from:

	systat bufcache

It is interesting.

Or copy and paste the memory lines from your top(1) that you are concerned 
with.
