named: high memory usage under FreeBSD-7...?

I'd recently updated a machine to FreeBSD 7-STABLE, and I've noticed that named from the base system (which claims to be BIND 9.4-ESV-R4) is using more than twice as much memory as it used to:
PID USERNAME THR PRI NICE SIZE RES STATE TIME WCPU COMMAND
706 bind 4 4 0 69424K 57292K kqread 0:09 0.00% named
It's serving about 20 zones with total record size of less than 100K, and has the following option block set:
This box was previously running FreeBSD-6.4 and dns/bind94 port, and named never crept above 30M VSIZE/RES even under heavy load (ie, "adnslogres -c 100" against a million line httpd-access.log file); the size above is from named running for about a day, *without* putting any significant load upon the nameserver....
