Yes, threads are enabled. I can try it with threads disabled and see if there is a difference. This is just a stock FreeBSD 7.0 system with BIND 9.5.0-P2 from ports. I'm not doing anything weird that I know of. Again, it also seems to happen on Windows, but as I understand, the ISC provided binary kit for Windows is threaded also, correct? I guess that could be the key. I will recompile without threads now and retest.
