[gentoo-user] something is filling up the filesystem

[Pupino]

Hi all,
i noticed a strange behaviour on my macine recently.
Something is continuously filling up my root partition at a speed near
1k per minute.
I have just few programs running and none of them should save that
much information on the disk.
Now the problem is that i have absolutely no idea of where to start to
investigate.
Anyone have ever got a similar problem?
Thanks to all,
Davide
