Secondary dns response is missing "ADDITIONAL SECTION"

Hi all

I've set up ISPConfig3 with two nameservers, ns11 and ns12. They're working so far. The only thing is that, when digging/looking up a domain, ns12 doesn't answer with an additional section.

ns11

Code:

dig @ns11.mydomain.me mydomain.me

; <<>> DiG 9.7.3 <<>> @ns11.mydomain.me mydomain.me
; (1 server found)
;; global options: +cmd
;; Got answer:

ns12.mydomain.me.		86400	IN	A	--ns12-ip--

ns12 is missing the ADDITIONAL SECTION. How can i fix this?

 

that fixed it. tailed syslog and found out that there were problems with syncing.

thanks
