Результат ps -elfT | wc -l равно 1331 И cat /proc/sys/kernel/threads-max возвращает мне 100000.
Вот как я запускаю свой docker, я использовал некоторые ограничения.
sh "sudo docker build -f Dockerfile-scraping --build-arg port=${PORT} -t ${DEPLOY_ENV} ."
sh "sudo docker run --pids-limit 100 -m 10G -d -t -p ${PORT}:${PORT} ${DEPLOY_ENV}"
I Я использую puppeteer@2.1.0 и моя версия сервера Debian9 .
