I'm trying to trace this in my project but can't seem to find out what the culprit is.
Any tricks to trace this to which node etc is causing node-red to exit and restart?
Happens about once every minute or two. Restarts.
NR is responsive until restart.Is that all the message you get?
What versions of node-red and nodejs (use node -v to get it) are you using?
What hardware/os are you using?
Do you recognise that IP address? The host appears to be vps-e031dc24.vps.ovh.net
Thanks for verifying the host name.. I got as far as ovh.net but nothing specific. Maybe I can trace code to see if there is any entry with that.
My current NR version is 2.1.4
Running on a Linux Ubuntu AWS EC2 service. t3a.medium as of now. I upgraded a step up to make sure I was clear on RAM at least, but never really maxed out even on the config prior...
And the nodejs version?
Sorry: Node Version is v12.22.4
Probably worth upgrading node red to the latest, unless that is a problem for you. Also make sure you are using the latest versions of all installed nodes (check in Manage Palette).
There are two issues
- Why is it trying to access that IP, which is presumably something in your flows
- Why does the timeout cause a crash. Upgrading node red and all the nodes might help with this one.
You didn't say whether that is the complete message. Can you post the node red log all the way from the startup the beginning of the next restart please.

You should set your own key using the 'credentialSecret' option in

I am currently upgrading NR and Node. I just got done, and I think I yet to have it restart... Will be watching, and update you later.
ThanksIf you upgraded nodejs make sure it is to v14 or 16, not an odd numbered one. It was the installed nodes that I was suggesting you should check for updates rather than nodejs. nodejs 12 is approaching end of life though, so probably a good thing to update anyway.
Yeah I went ahead and upgraded anyways...
The stable v16...
And NR to the latest...
I am still catching the error...
I will try and update the nodes via the pallet until it boots me...
I may need to look into how to update the nodes via command line.
What is the problem upgrading the nodes via Manage Palette?
Odd:
node -v v16.14.2
but NR reports its using v12
How did you install node-red and nodejs initially? Did you use the recommended Pi/Debian/Ubuntu script Running on Raspberry Pi : Node-RED
How have you upgraded nodejs?
What does
apt policy nodejs
show?
I generally install NR via the instructions at https://nodered.org/docs/getting-started/local
If I remember correctly this is how this instance was setup.
I used nvm to upgrade nodejs

It seems to not happen as often?

Started Node-RED graphical event wiring tool.```Not a good plan, I believe that installs nodejs in a different place to standard, so now you have both installed. In your position I would remove the nvm version and remove nvm, then I would use the script I linked to, with --node16 on the end (after a space). That should install nodejs 16 and ensure you are on the latest version of node-red.
As to the error, I think you need to find out what in the flows is trying to access that IP address.
