Cloud function getting stopped Parse.com in loop when calling from Arduino-yun
Give this a shot, I really hate String, maybe that 8-times thing has to do with memory issues caused by it.

void loop() {

  char functionToCall[8] = "meeting";
  Serial.println("Start loop");
  demoBasicCharArray(functionToCall, 0);
}


void demoBasicCharArray(char *functionname, int light) {

  Serial.print("In ");
  for (byte i=0;i&lt;sizeof(functionname);i++){
    Serial.print(functionname[i]);
  }
  Serial.println(" Function");

  ParseCloudFunction cloudFunction;
  cloudFunction.setFunctionName(functionname);
  cloudFunction.add("light_sensor", light);
  cloudFunction.add("value", "Arduino Hello");//parameters

  ParseResponse response = cloudFunction.send();
  Serial.println(response.getJSONBody());
}
