Hello
I have a question.
My develop resource
->EMQTTD MQTT BROKER
-> spring boot 2.0.3
compile group: 'org.eclipse.paho', name: 'org.eclipse.paho.client.mqttv3', version: '1.2.0'
senario
#1. publish simulator (10000 (300byte String) publish, per 1sec) qos0
/ test / monitor / 1 <--- publish
#2. subscribe qos0 simulator / test / monitor / 1
I found an error in this situation as follows.
MQTT BROKER did not stop
PUBLISH # 1 simulator did not stop.
This error only appears in SUBSCRIBE # 2. Is this a problem?
please .. help me
