Hey
With old version my ESP-07 module was having exception watchdog resets after disconnecting from MQTT and (straight after that) disconnecting from WIFI. Module was reseting in about 95% attempts.

Just replaced mqtt.c file with your version and so far my module is working fine as it is supposed to.
Was trying to find the problem for few days already. You made my day!

Thanks,
Luuke

@sifourquier You can try this https://github.com/vowstar/esp_mqtt, I'm testing and it is OK to safe disconnect MQTT client.
My branch is still under testing so I'm not create pull request to upstream, until it is stable.
You can use MQTT_Disconnect(MQTT_Client *mqttClient) to disconnect TCP connection,
and use MQTT_DeleteClient(MQTT_Client *mqttClient) to fully free the memory. When you delete client, you must redo MQTT_InitClient. When you use MQTT_Disconnect, need'nt re init client.
Please try.

To me, MQTT_Disconnect() should send a mqtt_msg_disconnect() message, message type MQTT_MSG_TYPE_DISCONNECT = 14. But that function isn't used.
