Привет, я использую веб-сервер ktor на кубернетах. При запуске экземпляра сервера он использует 250-300 МБ, но после нескольких часов работы использование памяти увеличивается до 600 МБ, и я установил ограничение на 600 МБ после перезапуска этого сервера из-за OOM. Для тестирования, когда память была 500+, я остановил весь трафик сервера c и сгенерировал дамп кучи, который прилагается ниже. Но проблема в том, что после нескольких часов ожидания память сохраняет 500+ МБ. Думаю надо go вернуть нормальные 200-300 Мб. Извините, я не умею проверять дамп кучи на наличие проблем. Не могли бы вы проверить это и сказать мне, где проблема, спасибо.
Сводка дампа кучи 
ссылка на полный дамп https://www.dropbox.com/s/sdmbgs41b8dgj38/ktor-app-dump.txt?dl=0 и здесь несколько дампов потоков
