ESP32CAM issue (Firebase + Hardware Serial problem)

[angelo31196]

Hi everyone, im making a code for ESP32CAM that recieves information from an arduino uno vía serial, im using the Rx/Tx ports of the ESP to program and display the info in the serial monitor, so i needed other pins to recibe and transmit information from/to an arduino, i used HardwareSerial to make pins 14 and 16 of ESP32CAM an extra pair of communication pins and it worked. Then i needed to connect firebase realtime database to the ESP32CAM, and i use a code that worked well without the hardwareserial, but when i try to use both the system starts rebooting (i imagine that is because a memory transgression, but i dont know). This is the code in the ESP32CAM, arduino send information of temperature and humidity in order. So, again , both codes work well alone, but together starts rebooting, what can i do?

#include <HardwareSerial.h>
#include <String.h>

#include <common.h>
#include <Firebase.h>
#include <FirebaseESP32.h>
#include <FirebaseFS.h>
#include <Utils.h>
#include <WiFi.h>

#define RXD2 16
#define TXD2 14

#define WIFI_SSID "MYWIFI"
#define WIFI_PASSWORD "MYPASSWORD"
#define FIREBASE_HOST  "MYHOST"
#define FIREBASE_APIKEY  "MYAPIKEY"

FirebaseData firebaseData;

HardwareSerial Serialinterno ( 1 );
String FromSerial;

void ToFirebase(String Path, String Value);

void setup() {
  Serial.begin(115200);
  Serialinterno.begin(9600,SERIAL_8N1,RXD2,TXD2); 
  WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
  Serial.print("Conectando a ....");
  while (WiFi.status() != WL_CONNECTED)
  {
    Serial.print(".");
    delay(300);
  }
  Serial.println();
  Serial.print("Conectado con la IP: ");
  Serial.println(WiFi.localIP());
  Serial.println();

  Firebase.begin(FIREBASE_HOST, FIREBASE_APIKEY);
  Firebase.reconnectWiFi(true);
}
void loop() {
  while (Serialinterno.available() > 0) {
         FromSerial= Serialinterno.readStringUntil('\n');
         FromSerial.trim();
         if(FromSerial=="Temperature"){
          String Temp = Serialinterno.readStringUntil('\n');
          Temp.trim();
          Serial.println("Temperatura: "+Temp);
          ToFirebase("/Temp",Temp.toInt());
          }
         if(FromSerial=="Humidity"){
          String Hum = Serialinterno.readStringUntil('\n');
          Hum.trim();
          Serial.println("Humedad: "+Hum);
          ToFirebase("/Hum",Hum.toInt());
          }
    }
}
void ToFirebase(String Path, int Value){
  if(Firebase.ready()){
    Firebase.setInt(firebaseData,Path,Value);
    }
  }

The error is this:

Rebooting...

Ok, i pass the exception by a decoder and says this. i can see that is a memory problem, but what can i do? the sketch have free space, so is very strange.
