"Success resolving" messages and can I Ignore them?

[Paul Ebersman]

martin> there is a recurring message in named.log that goes something
martin> like:

martin> success resolving 'www.pbs.org/A' (in 'pbs.org'?) after 
martin> reducing the advertised EDNS UDP packet size to 512 octets

martin> What category of message is this called and can I put something
martin> in named.conf similar to

martin> 	category lame-servers { null; };	

    category edns-disabled { null; };

should make you happier.
