allow-recursive question

[Mariano Cunietti]

Hi,
I have a problem with bind 9.2.1: I get thousands of these entries in
/var/log/messages saying "no more recursive clients: quota exceeded".

I run DNS service for an ISP with 5000 users. As far as I know, the
default limit for concurrent recursive clients is set to 1000. 

Should I disable recursive queries for users outside my networks? Would
there be any side effect? Which is a common policy for ISP's about
allowing external users to submit recursive queries?

Thanks in advance

Mariano
