Big problem with subdomains. Empty named zones

[barts]

Hello!

I created dns cluster (2 servers). In first server I have ns1.domain.com and second server: ns2.domain.com. When I try to synchronize all zones from first server to second cPanel create empty zones for example:

I have zone /var/named/some.com.db
and in this file I have 10 subdomain ex. aaaa IN A IP
when I make synchronize all (on Synchronize DNS Records) then cpanel create zone aaaa.some.com (in /etc/named.conf and /var/named/aaaa.some.com.db). This new file is empty and subdomain aaaa.some.com stop working!

I copy file named.conf from my backup to /etc/named.conf and it help me but I'd like to make sychronize all and start work second server in cluster.

1. How can I fast delete empty files from /var/named/*.db ?
2. How can I fix this bug?

It's bug in the last cPanel Relase ver.
I updated cPanel to last stable ver. and all is ok.
