Machine A is trying to access a filesystem on machine B via amd + nfs. Machine A first looks up machine B's AAAA record, this fails and then it looks up machine B's A record. This succeeds and the file accesses go through. However, when Machine B's named goes to lunch (this is the named that machine A is using), the query for the AAAA record times out and then the query for A happens some 30-45 seconds later and succeeds right away. At least that's my reading of the tcpdump traffic. None of these machines should be using IPv6 since we have no IPv6 machines and don't use IPv6 address. No AAAA records are defined at all. And it only seems to happen sometimes. I don't know what kills named in the first place, just what happens when it goes partially brain dead.
