I've had a look at other questions about this on the mailing list and they
all say that you are running out of space.  I set up a cron job to do a df
-i every minute, which does not show this to be my problem.

The following output from my /var/log/messages and df -i show what's
happenning.  The strange thing is that November 7 was a Sunday, and this a
proxy server at a secondary school.  (no one using the system) The df -i
output is from the same time as the third instance in the messages.

The only thing I've changed in the kernel is maxusers = 48 because I was
running out of file descriptors, and it's only started happenning since
then.

The machine is a PII with 2 x 4Gbyte SCSI discs, running FreeBSD 3.3
STABLE, Squid 2.2 STABLE5, dhcp and ipfirewall.  The cache directories are
in /home and /squid.
