В pf из OpenBSD 4.1, keep state делается по умолчанию.
Соответственно, нужно либо явно выключать его - "no state", либо
увеличивать число states - set limit { states XXXXX }.

Для 127.0.0.1 я бы без сомнений выключил:

 pass  in  proto tcp from 127.0.0.1 to port 9000 no state
 pass  out  proto tcp from 127.0.0.1 to port 9000 no state
