nscd cache reload does not occur at correct intervals for hostnames that have a CNAME record

Solution Verified - Updated -

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
