named: high memory usage...?

[Chuck Swiger]

Hi--

I'd recently updated a machine to 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:

options {
    directory "/var/named";
    recursive-clients 400;
    clients-per-query 210;
    max-clients-per-query 220;
    max-cache-size 10m;
};

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 millon line httpd-access.log file); the size above is from named running for about a day, *without* putting any significant load upon the nameserver....
