I have 128MB RAM and 256KB cache. My machine has been up 32 days. For
the first 3 weeks it went really nicely, didn't get anywhere near using
any swap. However this week it's usage has got over 100MB (now up to
120MB, after deducting buffers and cached, i.e. the second row of "free"
output) and there's plenty of swap being used! I just can't figure out
what's eating it. I wrote a script to total the figures produced by "ps
aux" in the VSZ and RSS columns. At present these come to:
192452 20612
respectively. To me this means there is only 20MB of RAM actually used by
processes, and the 192MB of virtual memory is probably not correct because
some is shared.
So: what's eating it? If it's any help, here's the output of some
commands:
% free
total used free shared buffers cached
Mem: 127756 126048 1708 17040 304 3528
-/+ buffers: 122216 5540
Swap: 128484 27208 101276

I just don't get it....any help? (I am running Debian rex, 2.0.27 kernel).
Is it a cache RAM problem (i.e. on 256KB)?
