OK problem resolved
Issue happened after centos yum update (in which was bind chroot updated)
DNS server in chroot was the cause for ispconfig config update not working.
steps
chmod 755 /var/named/
chmod 775 /var/named/chroot/
chmod 775 /var/named/chroot/var/
chmod 775 /var/named/chroot/var/named/
chmod 775 /var/named/chroot/var/run/
chmod 777 /var/named/chroot/var/run/named/
cd /var/named/chroot/var/named/
ln -s ../../ chroot
in ispc - management - server - dns
zonefiles dir -> change the value from /etc/bind to var/named/chroot/var/named
restart http + dns services in management or manualy
done
