I saw a problem a bit like this once on a potato machine running kde.
I can't remember the details, but there was a huge file of zeros
in a .kde directory or similar.
I found it by doing du -sh * from the top directory and following
down through the biggest ones until I found the file. Finding the
file will give you some clue as to its origin. Someone might
suggest a find command to find all the really large files in one go.

On my system they are logged into /var/log/kern.log*
I don't think they are likely to be the problem unless you either have
a tiny amount of free space or a _really_ busy site. These log files
normally amount to just a few megabytes.
There are a couple of ways to stop the logging to the console.
The only one I know off hand is a bit dirty - that is:
# echo "1 4 1 6" > /proc/sys/kernel/printk
to adjust the kernel logging levels. You could put it in a startup
script or just run it when you feel like it. Have a look at that file
to see what it is now.
There are much nicer ways though! It would be better for instance to
redirect all that stuff to one virtual console.
