Я использую довольно стандартный входной контроллер nginx с пустым configmap. Конфигурация nginx перезагружается (не перезапускается) каждую минуту или около того, и я вижу, как рабочие накапливаются в состоянии shutting down. Вот вывод ps aux

Как видите, каждый работник использует много памяти, поэтому использование памяти на этом компьютере выходит из-под контроля.
Значение worker-shutdown-timeout по умолчанию равно 10s, но эти рабочие отключаются на срок более 10 секунд. Кто-нибудь еще сталкивается с этой проблемой? Есть ли какой-нибудь способ для меня устранить это?
Вот отредактированные примерные строки из журналов
