Interesting that you have two devfs file systems, I have never seen one
dedicated to named before.
What slice are you using for squid? If you are using /var, it could be the
problem. Disks/slices generally dislike being run over 70-75% capacity.
Even though you generally don't want that much variable data on a home slice, I
would suggest either splitting your squid partition to use /home and /var,
(always nice to split then anyway AFAIK) or making the one on /var smaller.
Hope this helps
