I tried now

sudo -u bind ktrace -f /tmp/named.ktr named -g

But even with usually working config, named cant start calling him 
port(53).

kdump shows repeatedly:

  33246 isc-net-0039 CALL 
_umtx_op(0x8100384d0,UMTX_OP_CV_WAIT,0,0x8100384b0,0)
  33246 isc-net-0000 RET   _umtx_op 0
  33246 isc-net-0000 CALL  ioctl(0x16f,FIONBIO,0x7fffdffed17c)
  33246 isc-net-0000 RET   ioctl 0
  33246 isc-net-0000 CALL 
setsockopt(0x16f,SOL_SOCKET,SO_REUSEPORT,0x7fffdffed1bc,0x4)
  33246 isc-net-0000 RET   setsockopt 0
  33246 isc-net-0000 CALL getpeername(0x16f,0x7fffdffed108,0x7fffdffed0cc)
  33246 isc-net-0000 RET   getpeername -1 errno 57 Socket is not connected
  33246 isc-net-0000 CALL  bind(0x16f,0x80fa35948,0x10)
  33246 isc-net-0000 STRU  struct sockaddr { AF_INET, 127.0.0.1:53 }
  33246 isc-net-0000 RET   bind -1 errno 13 Permission denied

I never did nothing so deep in OS. What is wrong? I can send you full 
ktrace if it can help.
