Memory usage

[conaito]

I have add this onConnect: Serial.print("ESP32 FREE RAM: "); Serial.print(ESP.getFreeHeap() / 1024.0, 2); Serial.println("KB");

and connect and disconnect a client many times. As i can see the RAM goes smaller and smaller (even not much). May there is not correct free the memory on client disconnect? Can you double check that?

no leak

[conaito]

i will test it more and let you know. anyway main problem i have is the connection issue after a while of testing/playing with the broker. hope very much that you can find the issue. i will help, if i can with any required tests
