Утечка сокетов

[Artemiev Igor <ai@xxxxxxxxxx>]

Здравствуйте.

При некотором достаточно большом числе активных соединений (~6K) имею
вышеозначенную проблему - постоянно растущее количество соединений в состоянии
CLOSED. С debug_points abort удалось получить несколько корок на выходе.

nginx version: nginx/0.8.31
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 --with-file-aio 
--http-client-body-temp-path=/var/tmp/nginx/client_body_temp 
--http-proxy-temp-path=/var/tmp/nginx/proxy_temp 
--http-fastcgi-temp-path=/var/tmp/nginx/fastcgi_temp 
--http-log-path=/var/log/nginx-access.log --with-http_geoip_module 
--with-http_stub_status_module 
--add-module=/usr/ports/www/nginx-devel/work/nginx_upload_module-2.0.11 
--add-module=/usr/ports/www/nginx-devel/work/nginx_uploadprogress_module-0.7 
--with-pcre
