I edit /boot/loader.conf and added: kern.dfldsiz=900000000 kern.dflssiz=700000000 kern.maxdsiz=900000000 kern.maxssiz=700000000 kern.maxusers=512 And I recompiled Bind 9.3.2 and enabled the internal memory allocator. One thing I still get, which I dont understand why, is whenever I stop named, I get the following console error: Aug 31 23:47:57 cache01 kernel: Limiting icmp unreach response from 213 to 200 packets/sec Aug 31 23:47:58 cache01 kernel: Limiting icmp unreach response from 242 to 200 packets/sec Aug 31 23:47:59 cache01 kernel: Limiting icmp unreach response from 208 to 200 packets/sec Aug 31 23:48:00 cache01 kernel: Limiting icmp unreach response from 224 to 200 packets/sec As soon as I start named, it goes away. Any idea what this can be? -John
