Disk Space Problem

[Andrew Boothman]

Hi!

I'm having a bit of a problem with a 4.2-RELEASE box running natd 
and named to do NAT between my cable modem and an internal 
network of Windows machines (98SE & 2000)

df was showing that the /var filesystem was using 104% of its 
available space. When I looked at the drive, all I could see was that 
there was a huge /var/log/alias.log being created by natd, I wish I'd 
taken more care to note the actual sizes involved, all I remember is 
thinking that the file was very large.

So I moved /var/log/alias.log to /usr and touched a new alias.log. 
Unfortunately this didn't seem to make any difference, and the drive 
still read 104% full. Not really understanding, I decided to remove 
the -log flag from natd_flags in /etc/rc.conf and reboot the machine -
 just to play safe.

Sure enough when the machine came back up again it reports the 
/var filesystem as being only 4% in use.

Does anyone have any ideas about why this may have happened? 
I'm sorry I can't be more spacific about the exact numbers involved.

Thanks!
