Hello, Node Red is shutting down while running. Resource consumption is normal. I couldn't detect any errors. I couldn't find the log records. I am using v3.1.3
Hi, welcome to the forum.
Can you tell us the following:
- what procedure did you use to install node red?
- where is node red installed (docker? on a raspberry pi? windows computer? mac?)
- what version of NodeJs is installed?
Hello,
Sorry for the late response.
- I installed node redi via npm.
- installed on windows server 2012 R2
- Node.js version v16.15.1
I hope we can find a solution. When node-red closes, no log file is created and the cmd window closes.
Windows console applications do not log to file (or anywhere) unlike Linux. So you need to do this yourself. How you do this depends on how you start Node-RED.
So, what starts node-red? A service? A start-up script? A scheduled task? Manually via a terminal? Manually via a shortcut?
And which account runs node-red? The same account as logged in or as a separate account (like a service account or reduced privileges account)?
I start it manually on the terminal, through CMD.
In which case:
The terminal should remain open and you will see why it crashes.
If you want it logged to file, you need to redirect output to file.

hello, I still could not solve my problem. It stops for no reason. and Ram usage is increasing. waiting for your help.
Waiting for logs!
Can't help if you don't provide required info.
Did you look at the log? There is no evidence I can see that says node-red crashed. There are some errors in your function nodes.

I would start by addressing those issues in your function nodes.
Hello, can you also analyse this log? It looks like a memory error?

Yes, something is using lots of memory. First though address the earlier errors. They may not be related but they may be and are relatively simple to fix.
So how should we follow a way to detect what uses this memory. In my project, data from 6 machines is transferred to sql. A single sql node (mssql-plus) is used. Data from 6 machines are kept in a separate array and deleted as they are sent. When I follow, there is not much accumulation in the array.
Show us what the startup log looks like now please. You can put the log level back to info.
