/usr/sbin/named: symbol lookup error: /usr/sbin/named: undefined symbol: dns_dispatch_hash

up2date erased bind and bind-devel rpm and/ maybe also, removed user/group named

Note:- This was an issue on cpanel server, but same solution should work on other systems. ( on non cpanel systems, use  up2date -i  , instead of /scripts/ensurerpm
