check_http resolver (bug or me?)

[Arno Lehmann]

Hi,

what you describe seems to be a result of your resolver.

Most probably - but you would need someone who is more an expert 
concerning named and resolver than I am - you simply have a lame server 
that answers too slow, so that your local resolver sends the next query 
according to its search list.
