Hi, At the first sight it seems network problems, but when you restart bind, the problem goes away for a while. I suppose your dns server is resolving names for himself, try to put your ISP's dns servers on resolv.conf, perhaps it solve the problem. It could be a problem with your dns forwarders

Hi Mark, allow-recursion defaults to { localnets; localhost; };. If the client was not on a directly connected network it will NOT get recursion by default. So it would seem; I had made an assumption about subnetting that apparently was not entirely accurate. Oh well, you know what they say
