nscd cache reload does not occur at correct intervals for hostnames that have a CNAME record
Issue
- nscd ignores the TTL value associated with a CNAME record in a DNS query and uses the TTL value associated with the first A record instead.
- This results in incorrect cache refresh intervals for the hostname entry
Environment
