That sounds like a possible culprit: if these names take 12 steps of
recursion to resolve, presumably it's taking quite a long *time* to
resolve them - so if the cache is busy, it may be giving up on that
query while it's still part way through chasing all the levels of
recursion. Are you seeing any "drop" entries in the cache logs on the
affected machines?
