Eh?   I don't see anything in there pertaining to swap.  Those load numbers 
seem a little high to me,  though.  Maybe not.

I don't see where ps is going to help here either.  That's telling you what's 
running,  but doesn't address the issue of swap that I can see...

What I do here is set up "top" to run on tty8,  in the init scripts of each 
machine I set up (there are currently three of them with a fourth one in 
process).  At the moment,  the line in there that refers to swap reads as 
follows:

Swap:  248964k av,   29680k used,   219284k free                      27272k 
cached

Dunno why that "cached" bit is on that line.  This is with KDE up and kmail 
_only_ running at the present time.

Yesterday is a perfect example of the problem.  I had kmail up,  and also 
konqueror (where I think the problem lies),  and over a period of hours the 
swap used got all the way up to 111M!  The area around 20-30M seems to be 
typical when you first start it up.  Opening the browser and loading a web 
page will use some,  opening more tabs will drive things up,  and once you 
get up into the 50s things start to get *real* sluggish,  and you don't wanna 
use it any more.

At the moment I've got another machine on,  also on the LAN and working 
through the same firewall,  and that's got a lot more physical RAM in it, so 
that's where konqueror is running.   There's 320M in that box and the last 
time I looked it hadn't touched swap _at all_.  I have some more NFS tweaking 
to do before I get to the point were I'll be wanting to use mostly that box,  
but having started out using it,  I haven't noticed any particular pattern of 
RAM usage increasing.  Right now it's at 291012k used out of 321044k 
available.  We'll see if it increases or what...
