I can't reproduce here - I tried:
$ ./pdns_server --local-port=5300 --socket-dir=./ 
  --launch=random
  --recursor=8.8.8.8  --local-ipv6=::1
  --local-address=127.0.0.1

$ dig www.aol.com @::1 -p 5300
(SERVFAIL)
$ dig www.aol.com @::1 -p 5300
(SERVFAIL)
$ dig www.aol.com @::1 -p 5300
(SERVFAIL)
$ dig www.aol.com @::1 -p 5300
(SERVFAIL)
(etc)
$ dig www.aol.com @127.0.0.1 -p 5300
gets data

$ dig www.aol.com @::1 -p 5300
gets data too!

Perhaps you tried @localhost which might sometimes resolve to ::1?
