Hey gang,  
I was testing out a flow which would automatically reboot my RPi whenever the RAM usage was \>75% and somehow I've got it stuck in a bootloop.  
Can anyone suggest a way to get out of this, please?

I used an execute node with `sudo reboot`.

I'm guessing I'll need to pull the SD card and modify something, but I don't have another Linux machine to work on it.

Any help appreciated!  
Dax.

I think I got lucky. I kept trying and caught it at exactly the right moment and was able to disable the flow in the editor. Phew!!

To avoid this happening again, I've added a 5 minute delay to the output of the node.

Out of interest, how's my way of doing this?

```auto
var now = new Date();

if((msg.topic == "Memory") && (msg.payload >= 75) && (now.getHours() >= 3) && (now.getHours() <= 9))
  {
  msg.payload = 1;
  return msg;
  }
  
return null;

```

There is nothing wrong with what you are doing. You could be a bit more verbose for readability.

```javascript
const now = new Date();
const hh = now.getHours();

if (msg.topic == "Memory" && msg.payload >= 75 && hh >= 3 && hh <= 9) {
    msg.payload = 1;
    return msg;
}

return null;

```

Start node-red in safe mode `node-red --safe`
