If you are using pf, is it possible you are running into some state limit? On a system that is currently showing the nsd error messages, what does "pfctl -si" show? I would specifically look at the "memory" counter. If that counter is something other than 0 you are running into the current state limit (shown with "pfctl -sm"). Regards, Patrik Lundin
