День добрый !
После включения aio nginx временами начал "отжирать" всю доступную
память на сервере.
Памяти немного - 4Gb но и воркеров всего 4.
через 40 минут после запуска:
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 2641 0.0 0.6 105992 27464 ? Ss 15:25 0:00
nginx: master process /usr/sbin/nginx
www-data 2642 0.6 10.3 495964 418672 ? S 15:25 0:16
nginx: worker process
www-data 2644 0.6 9.7 474572 397280 ? R 15:25 0:16
nginx: worker process
www-data 2645 0.5 10.3 496348 419180 ? S 15:25 0:16
nginx: worker process
www-data 2646 0.5 10.4 501336 423956 ? S 15:25 0:16
nginx: worker process
параллельно с памятью растёт и "open files"
В логах, соответственно, вижу примерно следующее:
2009/10/14 11:18:19 [notice] 2667#0: signal 17 (SIGCHLD) received
2009/10/14 11:18:19 [alert] 2667#0: worker process 2670 exited on signal 9

единственное изменение к в конфигах которое сделал - на 5 сайтах
включил aio / directio
таким вот образом:
location /video/
{
internal;
root /home/www/beachhunters.com/members/;
aio on;
directio 1;
output_buffers 1 128k;
set $orig_type 'video';
post_action /download_stop;
}
и вот таким:
location ~* ^.+\.(avi|wmv|mpg|mpeg|mp4)$
{
aio on;
directio 1;
output_buffers 1 128k;
root /home/fhg;
if ($invalid_referer) { return 403; }
}
