Question about a high load BIND server setup...

[John Von Essen]

Okay, so this is where I am at.

sysctl tunables are standard, but somaxconn was bumped up to 512.

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?
