Sorry but we do not get core dumps on our systems! I have 4 other 
instances of named running and
they have not crashed so it might be a hardware problem. But I am 
suspicious as this box is running
everything else properly.

Is there anything I can switch on in the logs that might shed more light 
if it happens again.

For your information, the server was still running and servicing UDP 
traffic only the TCP side failed and
the crash seems to have happened in a child process.
