Yeah I used free, I never use nor trust top at all. And yes I did look
at the right row :-P
I started noticing this recently, specifically when I had my machine on
for 13 days. I noticed it was getting very very sluggish (my drives are
quiet so I don't notice the noise most people do when SWAP is in use),
and I ran free it showed like 17mb free RAM and almost half a gig of
SWAP.
So I exited X, shutdown all non-essential services (I have very few
running, this is a desktop). Basically with no process larger than
2-3mb the system was still without RAM and still using a ton of SWAP.
I'm keeping my eye open for who might be the culprit. I use a lot of
multimedia stuff on this machine so things like mplayer and X and such
that get left open for days when I'm away are possible culprits. I've
used Linux for years, I had a desktop machine running on a p166 for 6
months without a prob back in the days, but I've never seen memory
disposal like this...
