Problem Description

Ive been noticing memory leak issue with the built-in MQTT library. Im stress testing it with 500bytes and 1KB payload sizes. after a number of messages (around 200 for 1k and 400 for 500bytes) heap memory is almost completely consumed and the device crashes

Expected Behavior

MQTT_EXAMPLE: Free memory after recieving: 22340 bytes
MQTT_EXAMPLE: Free memory after publishing: 22340 bytes

Actual Behavior

I (306062) MQTT_EXAMPLE: Free memory after recieving: 22340 bytes
I (306072) MQTT_EXAMPLE: Free memory after publishing: 17804 bytes
I (306872) MQTT_EXAMPLE: Free memory after recieving: 21768 bytes
I (306892) MQTT_EXAMPLE: Free memory after publishing: 17232 bytes
I (307492) MQTT_EXAMPLE: Free memory after recieving: 21196 bytes

Steps to repropduce

vary the payload size to (1000+), and period to 500 to expedite the process
run the attached code
Publish a message to ESP32/Start
whenever a message is received to ESP32/data then publish to ESP32/ack
