столкнулся с проблемой завершения subprocess
У меня есть один главный бот, который запускает много дочерних ботов (система подписки в боте главном работает), когда подписка истекла, то дочерний бот должен выключится, при старте всех дочерних ботов я сохраняю их process.pid, чтобы потом по нему можно было выключить, но не получается сколько не пробовал
