Hi Wouter,
I think I have some thoughts on this issue. I had it happen again just before writing this email. It seems to happen after the system has been asleep for a long time, hours. When it wakes up it cannot get its act together and everything fails. I tried something tonight that resolved the problem: Unbound_control.exe flush_infra all This does something that causes unbound to sort itself out. And everything works again. Does this have something to do with time and DNSSEC or some other time dependant requirement? Hopefully you will be able to get something from the above and understand what is going on. This is a repeatable failure so long as you have a few hours to spare. I have not yet tried to work out how long the system has to be asleep for, this evening is was just about four hours. Let me know if I can provide any further information. RayG
