As a follow-up, I would like to note that this problem seems to have 
been partly resolved in v3.0 (final). I am running v3.0 Kees' CentOS 
RPMs with LDAP backend.

When the connection to the backend db (LDAP Server) is lost and 
re-established, there is no more pdns hanging, but results returned to 
DNS queries continue to be not always correct for the authoritative 
domain *when there is a pdns-recursor running on the same machine* (our 
normal setup).

I don't know what is happening, but "lazy-recursion=no", and all cache 
values are configured 0.

If the recursor service is stopped, pdns provides correct replies for 
the authoritative domain.

Please advise.
