Something must be wrong. It is really unlikely that the root file
system

Look at his disk. His root is the whole file system. /tmp/and /boot
don't take up room.

I am not sure what you mean by that. /boot and /tmp _do_ take up
space. They seem a little large for what he is doing, but I imagine
they (especially /boot) are a little large for what he is doing.

He has both a memory leak (using up swap) and a memory used up.

As for /swap, perhaps he is using a swap file and if so, it is
probably already formatted for swap and appears to be totally used.
That would be normal, though I would never use a swap file myself,
but a swap partition. This, per se, _does not_ indicate a memory leak
or exhaustion of memory.

This won't report if swap is partially used, only that 100% of the /swap
partition is occupied. If it's occupied by a swap file, that would explain
it, although it would be a bit odd.



Go to /var/ and make yourself some room.

While I prefer a separate /var partition, it is not absolutely
necessary. Having one might help the O.P. diagnose the problem if, as
I suspect, he does not run the normal cron stuff that manages
temporary files and logs.

Then as he suggests do
du -s /*
and look to see where the memory is being used.

This ain't memory, it's disk.

He should be able to do this right now.

Another possibility is that he installed _everything_ that comes with
his distribution instead of just the subset he needs.
Yee gads you have separate /usr, /usr/local, /home. He does not. If
you add yours up you get 7 GB used. (2.2G in /var? That is nuts!)

Well under 15G, don't you think?

Does that not depend on what I am doing?

Amen. A bit of web caching, a few MP3's and a few bittorrented CD images and
you can easily fill 15 Gig.
