Hi,

I've setup a firewall with a compact flash instead of a hard-drive.  This is
the output of mount:
/dev/ad0s2a on / (ufs, local, read-only)
mfs:17 on /var (mfs, asynchronous, local)
procfs on /proc (procfs, local)
mfs:36 on /dev (mfs, asynchronous, local)

As you see, I mount the compact flash as read-only and I setup a memory
filesystem for /var

In my rc.conf file:
diskless_mount="/etc/rc.diskless2"
varsize="131072"

Output of: df
Filesystem  1K-blocks   Used Avail Capacity  Mounted on
/dev/ad0s2a    229942 197570 13978    93%    /

5456    /var

It seems to have a big difference between the output of df and du.
My problem is, my /var partition is getting filled very quickly and I don't
know why ?  I don't know what to clean.  I've already deleted some log, but
I saved only 2% of free space or 1000 block.

I don't know what is taking all this space ?  Any ideas ?
