Коллеги, помогите пожалуйста со следующей проблемой:
Имеем:
freebsd 9.0,
php-fom,
bitrix
nginx/1.0.10

В какой-то момент начинаются сильные проблемы с отдачей статики, т.е. какие-то файлы просто перестают отдаваться и помогает только рестарт всего сервера!

В логах только записи следующего вида:

8 [info] 1692#0: *193 kevent() reported that client ***.***.***.*** closed keepalive connection
8 [info] 1692#0: *196 kevent() reported that client ***.***.***.*** closed keepalive connection
9 [info] 1692#0: *203 client timed out (60: Operation timed out) while sending response to client, client:
0 [info] 1692#0: *201 client timed out (60: Operation timed out) while sending response to client, client: ***.***.***.***
4 [notice] 1690#0: signal 15 (SIGTERM) received, exiting
4 [notice] 1694#0: exiting client timed out (60: Operation timed out) while sending response to client
