Start looking if limits for datasize is at default
(sweet% limit datasize
datasize        16384 kbytes ), increase if your DNS is anywhere 
near 16meg in size. (output of "top" will do)
If limit is to low, bind will crash. Change this, a good place is
/etc/login.conf, the section "daemon" (used by daemons, will be 
activated next reboot).

Also check if you have a decent amount of "free memory" (also in top)
If free memory is low, pagingh starts, and eventually processes
will be starved of memory. Correct if needed by installing more 
mem and increase swap.
