Update.  
The site has not crashed now for just over 40 hours which is a record.  
I started it in a cmd window with `node C:\Users\tbg\AppData\Roaming\npm\node_modules\node-red\red.js --max-old-space-size=8192`

I also got the code running to monitor the garbage collection. Here is a graph for the past 12 hours.

I have not had time to research each of the numbers yet, so am not sure what I am looking for / at.

The server was up for a record 9 days straight before a Windows Update nagged for a reboot.

I am going to take the solution to be running it with `--max-old-space-size=8192`.

Thanks everyone for your help - its a bit stressful having so many people expecting five 9's uptime!

so we dont know what really fixed the issue 😉

No I did not.  
It has an update/insert bug that prevents me from using it at the moment.  
So the fix is the only single change I made it would seem.
