OK - I'm normally on other end of such problems but I'm sitting here stumped as to where to start with this one!
I had a Pi3 connected to Neopixel cube, programmed with Node-RED and decided to take it to a Raspberry Jam to show it off last night.
I (very foolishly and I don't really know why I did it) decided to run the standard bash script to upgrade it from 0.19.x to 0.19.2 and now it simply locks up the whole Pi (becomes completely unresponsive over VNC and has to be rebooted) once the flows start up
I launch NR on my Pi by cd ing to /home/pi/.node-red and then typing node-red
it all is fine until the flows actually start running and then I can't do anything (Pi shows no activity on green light) and few secs later my VNC connection fails)
How do I start fixing this?
