Добрый день.
Столкнулся с проблемой утечки памяти.
Имеется иптв сервер, раздающий поток по http.
OC:
- FreeBSD 7.3-RELEASE-p1 i386
- FreeBSD 8.0-RELEASE-p3 i386.
В сервер приходят мультикаст потоки, которые с помощью udpxy
перегоняются в http.
Nginx выступает в роли фронтенда.
За пару часов его работы он может забрать порядка гигабайта памяти.
2692 www 1 4 0 258M 244M kqread 5 5:59 3.37% nginx
2691 www 1 4 0 18484K 5124K kqread 2 4:25 0.00% nginx
2693 www 1 4 0 166M 151M kqread 4 3:34 0.00% nginx
2690 www 1 4 0 119M 105M kqread 0 3:09 0.00% nginx
Версии пробовались:
- nginx/0.8.41
- nginx/0.7.67
- nginx/0.7.66
Результат одинаковый.
