I remember haveing read some discussion about that topic but thought it was fixed and haven't searched any further; thanks for doing that job :-) I can reproduce at any time, willing to test anything (which I can get to compile on stable/11)! This is a semi-productive machine where I evaluate some netmap/bhyve options/stragtegies. Thanks, -harry
