The classic cause of this is a large file that's been deleted (so it
doesn't show up in directory listings (or 'du')) but the file's still
open and being used by a process somewhere, so the kernel doesn't delete
it.
Once the process has closed the file, then it will be removed
altogether and the disk blocks freed up.
One possible cause of this could be some program or other that's
rotating log files, but the process doing the logging hasn't let got of
the old file yet.
If you can umount /var/log then the problem will dissapear, as it will
if you kill all processes using files on /var/mail. (anyone know how you
find out which processes are uisng files in a mount point?)
One other point, is that you _might_ have a corrupt filesystem.
If you do get it umount-ed, then run 'fsck' over it as well just to be
sure.
