AW: Limitation on concurrently handled queries

First of all thanks for the fast response. 

Maybe I misunderstood the Bind9 manual.
Bind9 ARM says:

recursive-clients The maximum number of simultaneous recursive lookups the server will perform on
behalf of clients

I understand that as recursive lookups that are issued to other name servers. The statement in the documentation and the parameter name doesn't say anything on iterative queries. And I read that statement - maybe I need new glasses - as a limitation applicable to forwarded lookups not resolved by the DNS master / slave zones locally available. So in my understanding it doesn't cover what I want.

Best Regards

Thomas Dangl

what's the point?

there's also recursive-clients option, maybe it's what you want?
