I've not found a solution. Despite updates to node-red, nodejs, and the contrib nodes I use it still dies about once every other day.
But the out of memory killer restarts node-red and everything is running fine again within 10-15 seconds. My system has been running 24/7 since my last post in this thread and I've never noticed the issue save for examining the log files I save daily.
I haven't tried removing the debug nodes, I'm still making a few tweaks and I need the nodes for testing/verifying any changes made. Maybe in a week or two I'll been done with the minor changes suggested by a fw months of actual real-world use, and then try removing the debug nodes.
