This is symptomatic of named hitting the datasize limit.
Which config option did you use? The cache size should
be limited by max-cache-size which is a soft limit and
should be less than datasize.
Note FreeBSD sets datasize to 512MB by default and you need
to reboot to reconfigure this upwards. See the FreeBSD
handbook for how to change this.
