Trying to debug bind 9.3.1 out of memory problem.

We're trying to run the port version of bind 9.3.1 on FreeBSD 5.3. The
system has 1GB of ram and only basic services are running on it, like sshd.
The number of zones is quite large and we expect named to use about 640 MB
The problem we are running into is that when named is started it starts
loading zones, when it hits 515MB in memory usage it stops loading zones and
complains it is out of memory. This is what top looks like:
Mem: 529M Active, 274M Inact, 143M Wired, 49M Cache, 111M Buf, 2556K Free
Swap: 2049M Total, 20K Used, 2049M Free
PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND
11609 root 96 0 516M 515M select 1:41 0.00% 0.00% named
The same DNS setup is running on a production server, BSD 4.3 with 1GB of
ram, version 9.2.x. So we know a previous version works with the same number
We've tried running bind 9.3.1 as user bind or root. We tried running it
chrooted and not. The default install of login.conf is being used and all of
the options are using "unlimited". But it seems that something on the OS
side is limiting ram usage of 9.3.1, we're thinking.
Any suggestions on options or debugging tricks I can apply?
