Hmm, these are not a direct evidence, but it seems the server really
has a very many number of open UDP sockets. I don't think it matters
much, but just in case, is there any change if you build named
with/without threads (and with FD_SETSIZE=4096)?

I'd like to know some other information that may matter:
- How many queries per second is that server normally accepting?
- What's the normal cache hit rate (you can identify it via rndc stats
outputs)?
