Very interesting. We have the exact same issue, and our symptoms are
also the same. We periodically have to restart NSD to alleviate server
load. Wouter Wijngaards and I have been trying to find the problem for
ages, and we both thought it was in NSD. I've been trying various
patches he made, but nothing has helped, and now it seems clear why,
because the bug isn't in NSD. Of course, NSD's frequent forking probably
makes this worse, and on our server with several thousand zones, the
zone refresh rate is quite high.
