Приветствую, коллеги. Nginx используется как прокси к apache2.
Конфигурация изменяется очень часто с помощью самописного генератора шаблонов и выполняется reload.
Доменов > 600.
В статус компоненте постоянно вижу увеличение цифры в значении Writing, и значения сильно выше реальной нагрузки.
Ощущение, что часть writing не закрываются вообще. Помогает только nginx restart.

We experience the same issue as well.
nginx version: nginx/1.12.1
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC)
We have multiple servers with the same nginx build, but servers which don't serve http2 don't have this problem, so I guess the leak is somewhere in http2 code.

Status: newclosed

A number of leaks in the HTTP/2 code were fixed recently, should be fixed now, so closing this.
