There is more resources then MBUF's ( which you don't see, to lack.

How about the "limit's" for named ? 
I get : 
> limit
cputime         unlimited
filesize        unlimited
datasize        524288 kbytes
stacksize       65536 kbytes
coredumpsize    unlimited
memoryuse       unlimited
descriptors     957 
memorylocked    unlimited
maxproc         478 
On a 4.4 : FreeBSD zap.manet.nu 4.4-STABLE FreeBSD 4.4-STABLE #1: Thu Jan 17 21:27:09 CET 2002     root at zap.manet.nu:/usr/src/sys/compile/ZAP  i386

which is funny since my login.conf specifically uses "umlimited' ...

A datasize limit of 524288 would stop a nameserver after a while.

Sorry about not beeing able to solve your problem, but this is a road 
to follow. Try : limit datasize unlimited before starting named and
see if named can grow above the size it has now. If so then the 
default limits should be changed. ( if you run named as user named, go
for an entry for "named" in /etc/login.conf )

/etc/login.conf seems to be a hashed database, cap_mkdb seems to 
be used to rebuild the database. ( in 4.3 i don't see a hached database
at all )
