Это разные “лёгкие” устройства, которые подключаются к MQTT - шлюз чайника Redmond, ноутбук (и читал MQTT через MQTT.fx), часы на базе ESP8266 (читают с WB температуру и влажность в помещении, чтобы выводить на экран). У них нагрузка совсем не большая, и именно на чтение.
Попробую отключить, сообщу тогда через сутки.
Перед “отвалом” mosquitto я еще обратил внимание на malformed packet - тоже похоже на явного “предвестника”
