Should it not then be called > "max-queries-per-client" and > not "max-clients-per-query"? Oops, I was wrong. I was confused about the case where a single (or multiple) client keeps sending a high volume of different bogus queries (for which max-clients-per-query doesn't help). I now see the problem. It's really strange to have more than 10,000 recursive clients for the same query while max-clients-per-query is 100. I have no specific idea about how this could happen, but I'd suspect this may be a thread-related bug. Is it possible to rebuild named without threads and see if the same problem happens? --- JINMEI, Tatuya Internet Systems Consortium, Inc.
