Trouble forwarding queries

Some time last night bind seems to have stopped forwarding queries. 
This is the error bind logs.

15-Jul-2011 09:30:10.074 resolver: debug 1: createfetch: A
15-Jul-2011 09:30:10.074 query-errors: debug 1: client query failed (SERVFAIL) for at query.c:4020

tcpdump show no traffic to or from the upstream dns servers.

Here's part of the named.conf:

options {
     allow-transfer {
     forwarders {;;
     directory "/etc/namedb";
     version "BWSS DNS";
     auth-nxdomain no;

     allow-recursion {;; };

# named -V
BIND 9.7.0-P1 built with '--prefix=/usr' '--mandir=/usr/share/man' 
'--infodir=/usr/share/info' '--sysconfdir=/etc/bind' 
'--localstatedir=/var' '--enable-threads' '--enable-largefile'

'--with-geoip=/usr' '--enable-ipv6' 'CFLAGS=-fno-strict-aliasing 
-DDIG_SIGCHASE -O2' 'LDFLAGS=-Wl,-Bsymbolic-functions' 'CPPFLAGS='

Any idea where I shoud look?
