DNS BIND dispatch errors

[Simon Waters <simonw () zynet net>]

The increase in dispatch errors reported by BIND recently is explained by the 
other ISC here;

So it looks like the error message was right, although some older versions of 
BIND didn't do a good job of reporting the IP addresses involved.

My own experience was the servers mentioned here aren't the only servers doing 
this rather bizarre behaviour, but it is likely they could account for the 
increase seen (in association with a spam run causing lookups).
