Стоит freebsd 6.2, прозрачный squid 2.6.STABLE18 с pf

Конфиг squid:

В если в браузере набрать http://192.168.14.1:3128, то squid начинает ломится сам к себе и подвисает с с ошибкой:
"httpAccept: FD 24: accept failure: (23) Too many open files in system"

Можно конечно решить проблему следующим:
acl to_self dst 192.168.14.1/32
acl from_self src 192.168.14.1/32
acl squid_ports port 3128
http_access deny from_self to_self squid_ports
но нету ли решения покрасивее?
