Hello my fellow sluggers,

I found the / partition had filled on one of my routers.

Filesystem Size Used Avail Use% Mounted on
/dev/hda2 2.7G 2.7G 0K 100% /
none 31M 0 31M 0% /dev/shm

The /var/log/wtmp file had grown to 1.6G. I deleted it, and touched a new
wtmp. The new one has grown to 1M in just under an hour. My log fills with
these entries from c{1-6}.
