Re: nginx & core dump

["ak84" <nginx-forum@xxxxxxxx>]

Максим, доюрый день.
Спасибо за ответ, попробую с новой стабильной версией из портов.

Чтобы не плодить темы:
Есть 2-й сервер, на нём установлена: FreeBSD 8.2-RELEASE-p3 amd64
nginx -V
nginx version: nginx/1.2.3 ( самая свежая версия из stable )
TLS SNI support enabled
configure arguments: --prefix=/usr/local/etc/nginx --with-cc-opt='-I
/usr/local/include' --with-ld-opt='-L /usr/local/lib'
--conf-path=/usr/local/etc/nginx/nginx.conf
--sbin-path=/usr/local/sbin/nginx --pid-path=/var/run/nginx.pid

В dmesg вижу:
