[Pdns-users] strange answers from pdns 3.0-rc1 with recursor=8.8.8.8

[Vasiliy G Tolstov]

I'm using pdns-3.0-rc1

if i dig www.clodo.ru on 188.127.244.30 like: 
dig @188.127.244.30 www.clodo.ru A

first answer is correct:
cc00:~ # dig @188.127.244.30 www.clodo.ru A

; <<>> DiG 9.5.0-P2 <<>> @188.127.244.30 www.clodo.ru A
; (1 server found)
;; global options:  printcmd
;; Got answer:

But second is incorrect:

cc00:~ # dig @188.127.244.30 www.clodo.ru A

If i wait some time (about some seconds) next answer is correct, but
after that i get incorrect answers... 
But if i dig from recursor - all answers is correct at any time
