Hi Thomas. Firstly, I doubt you actually need to kill and restart `named`. Flushing the cache would probably work, either all of it or just selected names.
Secondly, take a packet capture of this happening and analyse what BIND is really doing, in Wireshark. - If it shows up that certain NS are causing the problem you can avoid them, in config. - If it's a DNSSEC issue, you can get around that on a per-domain basis, if needed. - If it turns out that qname minimization is the issue, you can play with settings for that, too. In short, there are plenty of tools in the kit bag. But understand what the problem is first and to do that, gather data (pcaps and logs) that can be used to paint a picture of what's really happening.
