Is there any routine able to output through serial monitor the amount of ffee memoru in the ESP8266?

I'm using the arduino IDE to compile my projects. I'm making use of MySQL Connection and getting constant hangs. Very frustrating. I'm trying to figure if it's memory related or not.

Thank you,

/* Serial.print("ESP.getBootMode(); ");
Serial.println(ESP.getBootMode());
Serial.print("ESP.getSdkVersion(); ");
Serial.println(ESP.getSdkVersion());
Serial.print("ESP.getBootVersion(); ");
Serial.println(ESP.getBootVersion());
Serial.print("ESP.getChipId(); ");
Serial.println(ESP.getChipId());
Serial.print("ESP.getFlashChipSize(); ");
Serial.println(ESP.getFlashChipSize());
Serial.print("ESP.getFlashChipRealSize(); ");
Serial.println(ESP.getFlashChipRealSize());
Serial.print("ESP.getFlashChipSizeByChipId(); ");
Serial.println(ESP.getFlashChipSizeByChipId());
Serial.print("ESP.getFlashChipId(); ");
Serial.println(ESP.getFlashChipId());
heap = ESP.getFreeHeap();
