free space reports

[Yaroslav Halchenko]

I'm getting confused with one of the hosts reporting low space in one of
the partitions:

when I df  it, it shows plenty of space:

ravana[0] /boot/fai/pxelinux.cfg>df /var
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda7              1542156    995644    546512  65% /var

and if I manually run cfagent -v then I get

Checking free space on /var
Free space above -20, defining 

so everything looks ok...

does it mean that I have some beast process which dumps 0.5GB into var
from time to time and removes it immediately? or there is something else
to check for?
