glibc (2.5-5) unstable; urgency=low

  Since this release, hosts caching in nscd is off by default: for some of the
  libc calls (gethostby* calls) nscd does not respect the DNS TTLs.  It can
  lead to system lockups (e.g. if you are using pam-ldap and change the IP of
  your authentication server) hence is not considered safe.

  See debian bug #335476 and how upstream answered to that in
  http://sourceware.org/bugzilla/show_bug.cgi?id=4428.
