Добрый вечер.
В продолжение темы http://forum.nginx.org/read.php?21,230962
Перевёл nginx на обновлённую ОС: FreeBSD 8.2-RELEASE-p3, обновил nginx ( из портов):
nginx version: nginx/1.2.4
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 --error-log-path=/var/log/nginx-error.log --user=www --group=www --with-debug --http-client-body-temp-path=/var/tmp/nginx/client_body_temp --http-fastcgi-temp-path=/var/tmp/nginx/fastcgi_temp --http-proxy-temp-path=/var/tmp/nginx/proxy_temp --http-scgi-temp-path=/var/tmp/nginx/scgi_temp --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi_temp --http-log-path=/var/log/nginx-access.log --add-module=/usr/ports/www/nginx/work/agentzh-headers-more-nginx-module-6586984 --with-http_image_filter_module --add-module=/usr/ports/www/nginx/work/yaoweibin-ngx_http_substitutions_filter_module-27a01b3 --with-http_stub_status_module --with-pcre --with-http_ssl_module

В dmesg вижу:

Смотрю core-файл:
