Error: The connection was lost about umqttbroker HOT 7 OPEN

The program defines a custom broker class with callbacks, I connect from a remote client and publish as below. After 6 iterations, I have the following message "Error: The connection was lost"MQTT client: ***@***.***: mosquitto_pub -h 192.168.7.237 -p 1883 -t "MQTT_ref" -m "400" After 1st iteration, program works well ***@***.***: mosquitto_pub -h 192.168.7.237 -p 1883 -t "MQTT_ref" -m "400" ***@***.***: mosquitto_pub -h 192.168.7.237 -p 1883 -t "MQTT_ref" -m "400" ***@***.***: mosquitto_pub -h 192.168.7.237 -p 1883 -t "MQTT_ref" -m "400" ***@***.***: mosquitto_pub -h 192.168.7.237 -p 1883 -t "MQTT_ref" -m "400" ***@***.***: mosquitto_pub -h 192.168.7.237 -p 1883 -t "MQTT_ref" -m "400" after 6 iteration, MQTT broker is down with the following message Error: The connection was lost.MQTT broker running on ESP8266: #include "uMQTTBroker.h" #include <ESP8266WiFi.h> #include <ESP8266HTTPClient.h>int ref_index=0; char ssid[] = "your SSID"; // your network SSID (name) char password[] = "your password"; // your network passwordclass myMQTTBroker: public uMQTTBroker { public: virtual bool onConnect(IPAddress addr, uint16_t client_count) { Serial.println(addr.toString()+" connected"); return true; }virtual bool onAuth(String username, String password) { Serial.println("Username/Password: "+username+"/"+password); return true; } virtual void onData(String topic, const char *data, uint32_t length) { String temp; char data_str[length+1]; os_memcpy(data_str, data, length); data_str[length] = '\0'; Serial.println("received topic '"+topic+"' with data '"+(String)data_str+"'"); if (topic == "MQTT_ref") { temp = String(data_str); ref_index= temp.toInt(); Serial.println("MQTT OK"); } } }; myMQTTBroker myBroker; void setup() { Serial.begin(9600); WiFi.begin ( ssid, password ); // Attente de la connexion au réseau WiFi / Wait for connection while ( WiFi.status() != WL_CONNECTED ) { delay ( 500 ); // Connexion WiFi établie / WiFi connexion is OK }Serial.println("Starting MQTT broker"); //// Start the broker myBroker.init();myBroker.subscribe("#"); //Subscribe to anything } void loop() { Serial.println("loop"); delay ( 3000 ); }— You are receiving this because you are subscribed to this thread.

I did several test with LwIP v2 lower Memory , Higher Memory (no features), ... It does not work with LwIP v2. I compiled with v1.4 Higher Bandwidth and it works !!!! Thank you -:) Can I keep v1.4 version for the project or did you find a workaround with v2 ?— You are receiving this because you commented.
