 Does switching it off help?
 
 From ip(4):
 
  Ports are allocated at random within the specified port range in order to
  increase the difficulty of random spoofing attacks.  In scenarios such as
  benchmarking, this behavior may be undesirable.  In these cases,
  net.inet.ip.portrange.randomized can be used to toggle randomization off.
