Здравствуйте!
Есть проблемка с nginx на Solaris.
При совсем небольшом аплоаде (~100Mb/s) нгинкс перестает отвечать,
воркеры не возможно убить даже через -9.
Есть подозрение что это проблема Solaris а не nginx, но может кто-то
сталкивался.
В еррор логах ничего необычного, в момент подвисания в логи ничего не пишется.
На FreeBSD такая схема работает отлично с аплоадом в 300Mb/s..
