In addition to the login.conf/limits hint, check the sysctl
kern.maxfiles
and
kern.maxfilesperproc

Note that bind opens two listening sockets per configured IP address. If
you have several aliases on one interface it'll open 2*#IPs and probably
hit the limit. You probably want to limit named to binding to specific
IPs; see the 'listen-on' option, e.g.
options {
listen-on { 127.0.0.1; 192.168.1.2; };
};
