Node Red crashed - why?

Flixm · 7 March 2022 16:15

Hi,
the last time neary every day my Node Red restart by itself and i could not find out why.
I worked with a few charts the last time. Maybe that could be a reason ?

Attached the LOG of the "restart":

The Node Red is running on a Pi 4 2GB

Maybe someone could help me run out of this problem

Colin · 7 March 2022 16:32

It could be the charts, or are you manipulating images or video or something that consumes large amounts of memory?

How many charts have you got, how many lines on each chart, at what rate is new data added to the charts and what is the time range specified for the charts?

Flixm · 8 March 2022 05:57

Hi,
Actually I have 2 chats. One with 4 lines every minute about 3 days, and another one with one line every minute.
What is the best setting for a chart?

Flixm · 8 March 2022 08:21

Is it the memory RAM ? Or the size of the SD-card from the pi?

Colin · 8 March 2022 09:54

Once a minute is 1440 per day, so if the chart is three days then each line will have 4320 points on it. You have a lotal of 5 lines across the two charts so that is a total of 21,600 points to be shuffled down the chart once a minute. That is quite a lot but will certainly not cause it to run out of memory.

Yes it is RAM that is running out.

Can you post more of the log please, from well before the crash to after the node-red startup messages please.

... and then a regular startup without any abnormalities.

I think there are two options:
1st -> i need a Pi 4 with 4GB Ram
2nd -> i send the values to Google Tabs and create a chart to check the last days (also more then 3).

For the next days i stoped the charts, cause I'm on a buisness trip.

I read something about --max-old-space-size can i do something with this information in my case?

Colin · 9 March 2022 09:20

Did you use the recommended script to install node-red?

Please show us the section of the startup log that you snipped as the "regular startup" log.

Also please post the file /lib/systemd/system/nodered.service

Flixm · 11 March 2022 16:34

... I think I did it correct. I did it as written in the description.

3 days ago I change the timing to every 15 minutes.

Since then no crash

Tassidar · 22 March 2022 13:58

Hi Everyone,

this is my first post. I've been using Node Red for a while and I'm quite happy with it.

Since it was lots of fun and no real problems, I didn't need to ask for help... until now

Today I accidentally started an infinite recursion of an external Python-Script. (via exec-Node...)

Well, infinite was a little too much for my poor ol' Pi4 with just 2 GB, and so I crashed Node-Red.

I figured, that when I move the Script somewhere else and restart my PI, that everything would come back to life, but no.

Do you have any Idea how to revive it?

Here is a snippet of log, that node-red gives me, when I run it manually (did do a proper "sudo service nodered stop" before...

Welcome to the forum @Tassidar

Generally it is best to start a new thread rather than replying to an old one, unless you believe that the cause is the same as the previous thread. I will ask some questions, if you could start a new thread, and provide the answers to those questions, as well as the information you posted, then that would be best.

Does it fail very soon after the mqtt broker message or is it some time later?

Was it working ok and then failed? If so then did you change anything?

Should it connect to the mqtt broker ok?

dceejay · 22 March 2022 17:43

you can possibly start node-red with the --safe command line option to start but not run. You can then tidy up whatever is causing the issue and deploy.

Tassidar · 22 March 2022 18:30

Thank you. Yes, that did solve my problem.

Happy to be up-and-running again
