Go to the exec.php page.  Do a "df -h" and report here.  Should look like;
$ df -h
Filesystem   Size   Used  Avail Capacity  Mounted on
/dev/md0c     11M   9.9M   791K    93%    /
/dev/ad0a    6.7M   5.4M   1.3M    81%    /cf
procfs       4.0K   4.0K     0B   100%    /proc

While there go ahead and grab the file /var/db/dhcpd.leases and post it. (If 
it isn't too big.  Just the size if it is)

Could be a broke client renewing IP addresses constantly and filling the 
file system.
