I have a nice ThinkPad 360CE (I think). I am a relative newbie to NetBSD
and I am unsure of what is eating my memory. It seems like processes
with PIDs 2 through 8 (presumably spawned by init?) are, together,
gobbling 12MB of my 20MB of RAM (WTF???).
Here is the output of 'free' (yes, it is a script which emulates the Linux
command of the same name):
total used free buffers
Mem: 13544 12532 1012 0
Swap: 66020 0 66020
And here is the output of 'ps auxw':

What in heck are these things, and why are they eating all of my RAM!?
About all that I can guess at are pcic0,0,[01] (i.e. my PCMCIA drivers,
no?) and pagedaemon (some sort of swapspace handler)? And reaper, I
suppose, kills old tasks?
Why are these things eating so incredibly MUCH RAM?
