Random restarts

Hi

Node red randomly restarts and I am not quite sure how to interpret it.
I just started over a week ago and nothing new was added to any flows.

In the log I managed to get the following:

This line is telling you node-red has been crashed unexpectedly by "something"

This line tells you which node that is.

It looks like a known bug as it has been reported here: unifiWS stability issue · Issue #128 · Isaksson/node-red-contrib-unifi · GitHub

The author was unaware of it and may think it is an isolated case, you should probably comment on the issue to explain how you also encountered it.

Thanks, @Steve-Mcl
I don't use the unifi nodes as it is right now, so I just disabled it for now.

So the way it is shown, it just shows that the entire node module is at fault, and not a specific part of my programming in the flow where I use the node. Right?
Because that was what I were looking for :slight_smile:

Hello.
I have released a new version that fixes this issue.
