Salve linuxers...

Alguém poderia traduzir as 2 linhas abaixo do log do meu NAMED?


Sep 26 09:36:30 belluzzo named[14911]: clients-per-query increased to 16

Sep 26 09:43:52 belluzzo named[14911]: unexpected RCODE (SERVFAIL) resolving 'www1.ins.dell.com/A/IN': 201.10.120.2#53

A quem possa interessar, sobre o dump "clients-per-query" do Bind que aparece no meu log, encontrei no site oficial do Bind a documentação:


________________________________________________
clients-per-query, max-clients-per-query

These set the initial value (minimum) and maximum number of recursive simultanious clients for any given query (<qname,qtype,qclass>) that the server will accept before dropping additional clients. named will attempt to self tune this value and changes will be logged. The default values are 10 and 100.

This value should reflect how many queries come in for a given name in the time it takes to resolve that name. If the number of queries exceed this value, named will assume that it is dealing with a non-responsive zone and will drop additional queries. If it gets a response after dropping queries, it will raise the estimate. The estimate will then be lowered in 20 minutes if it has remained unchanged.

If clients-per-query is set to zero, then there is no limit on the number of clients per query and no queries will be dropped.

If max-clients-per-query is set to zero, then there is no upper bound other than imposed by recursive-clients.

Mas ainda preciso descobrir o que é esse...
