Имеем набор:

Стоит FreeBSD 7.0 в качестве сетевого экрана был выбран недавно портированный из OpenBSD пакетый фильтр PF. Далее на машине установлен Squid 3.0, сейчас уже обновлённый до "Squid Cache: Version 3.0.STABLE11", раньше сквид использовался явным способом но помере чтения и сёрфа в интернете узнал что есть прозрачное проксирование. Теперь уже 4ый месяц работает прозрачно. Далее, установлен MPD5 Version 5.2 долго бился но в итоге победил проблему чтобы ВПНщики видели локалбную подсеть.....

Итак а теперь имеем следущие проблемы в данной систме:
Все пользователи из локальной и впн подсетей прзрачно проксируются по http, иногда я что то меняю в конфиге сквида, а порой сквид сам перезагружается предварительно сея в конфигах:

cache.log:
2009/02/08 09:51:27| assertion failed: store_client.cc:430: "STORE_DISK_CLIENT == getType()"
2009/02/08 09:51:31| Starting Squid Cache version 3.0.STABLE11 for i386-portbld-freebsd7.1...
2009/02/08 09:51:32| Pinger exiting.

и в мною созданном благодаря syslog`у в /var/log/squid.log
Feb  8 09:51:28 213-183 squid[4783]: Squid Parent: child process 4785 exited due to signal 6
Feb  8 09:51:31 213-183 squid[4783]: Squid Parent: child process 68993 started

и такие перезагрузки бывают абсолютно в разное время как видим по дате и времени Feb  8 09:51:31 утром когда пользователей было не так уж и много...

Итак я может и не заметил бы этого если бы сквид мог свободно сам перезапускаться.
Он зависает, причём даже если я делаю squid -k reconfigure он всеравно зависает.
При рестарте происходит следуее:

и т д я в это время пытаюсь сделать squid - shutdown не помогает, причём смотрите что выдат команда:

ivc_router /# ps -ax | grep squid
72569  ??  Is     0:00.00 squid -D
76911  ??  I      0:00.13 (squid) -D (squid)
77123  ??  Ss     0:00.00 squid - k shutdown
77144  ??  Ss     0:00.00 squid - k shutdown
77184  ??  Ss     0:00.00 squid - k shutdown
77207  ??  Ss     0:00.00 squid - k shutdown
77245  ??  Ss     0:00.00 squid - k shutdown
77304  p0  R+     0:00.00 grep squid
76908  p1  S+     0:00.00 tail -f /usr/local/squid/logs/cache.log

Обратите внимание на номера процессов "squid -D" и "(squid) -D (squid)" обычно они разлчаются на 1-2 единицы...
Убить сквид помогает только команда "killall squid",
Далее сквид не запустить командой "squid -D" он опять же зависает. Запустить удаётся сквид только тогда.... ))) когда PF превращаю в "дырку от бублика" тобишь когда в
pf.conf:

pass all

После этоих "шаманств" я делаю squid -D и обратно применяю "нормальные" не дырявые правила pfctl -f /etc/pf.conf.  И всё работает, но стоит звёздам сгуститься на небе сквид сново перезапуститься и мне опять будут звонить на трубу и гундеть, гундеть и гундеть....
