Description Paulo Andrade 2018-04-16 20:40:46 UTC 
There is a bug report and patches at
https://sourceware.org/bugzilla/show_bug.cgi?id=15862
[nscd doesn't cache record containing more than one IP address.]

  Not specific to rhel6, as the patches are not in any upstream
version, is there some plan to implement the patches in sourceware
bugzilla?

glibc-2.12-sfdc02079051.patch

  It was explained that some software was doing gethostbyname on a server
with multiple ip addresses, and the proper solution would be for such
software to be adapted to use getaddrinfo (mostly based on information
at https://www.akkadia.org/drepper/userapi-ipv6.html).
  User temporarily switched to a single address in /etc/hosts for the server.
  Now the user is testing a rhel6.9 package built with the attached patch,
that is a minor adaptation of the related patches attached to the sourceware
bugzilla.
Comment 4 Florian Weimer 2018-04-24 15:16:23 UTC 
As Carlos explained in bug 576801 comment 11, we did not plan to make the change in Red Hat Enterprise Linux 6 at the time, and reconsidered the change for Red Hat Enterprise Linux 7.

Adding more IP addresses visible to applications is a change which will break expectations of some users, so it is not appropriate for Red Hat Enterprise Linux 6, which is now in Maintenance Support 2.
