Still too much blood in my caffeine stream.... IIRC, someone was asking
about a problem with DNS queries and IPv6 yesterday. I just got a
notification from RH this morning, about a glibc bugfix update, and
wondered if this might impact that problem....
Excerpt:
This update fixes the following bug:
* Prior to this update, glibc incorrectly handled the "options rotate"
option in
the /etc/resolv.conf file when this file also contained one or more IPv6 name
servers. Consequently, DNS queries could unexpectedly fail, particularly when
multiple queries were issued by a single process. This update fixes
internalization of the listed servers from /etc/resolv.conf into glibc's
internal structures, as well as the sorting and rotation of those
structures to
implement the "options rotate" capability. Now, DNS names are resolved
correctly
in glibc in the described scenario. (BZ#843571)
