Uncertain if this is related, but on my systems nscd unloads itself after a 
(very) short time. Starting "nscd --debug" as root reports:

  5066: Reloading "ad.doubleclick.net" in hosts cache!
  nscd: cache.c:335: prune_cache: Assertion `dh->usable' failed.
  Aborted

This appears to be a rather well-known bug, see:

If I understand correctly, the cause is a corrupted nscd database.
