Over the last few months, I've been using Node-RED in the context of EVSE (Electric Vehicle Supply Equipment) development. I'm using Node-RED (v3.0.2) in a Docker container installed in an OEM device. For context, in the flows I've been developing there are both Modbus and CAN communication with e…

The problem happens even without the dashboard, I don't understand your point. I'm storing some data, but I wouldn't say it's enough for the system to run out of memory. Yes, I'm using arrays but with a fixed size. As I told you, it is Linaro (Lightweight Linux Distro.).

It is to see if Node-Red is running smoothly or not. I am at the bottom of the barrel for ideas on what to do.

Hello Colin. If I disable all flow tabs, except the one with the LED blinking, it seems that it doens't pause. And yes, I meant a real LED and not a Dashboard LED.

Seems @TotallyInformation has explained what I was trying to say a lot better.

Yes, I agree with you. We are trying to make an effort to have more crucial information available for those who are developing. Look at this message that the OEM manufacturer sent me a few days ago when we were discussing about my issue: "Hello Gonçalo, we are now finished our investigations and…

@TotallyInformation Look at this answer from the OEM manufacturer.

I run node-red on numerous low power devices, old Pi Zeros for example. As long as one is not doing anything massively intensive then I don't see pauses. At least not often enough to notice. How often are you triggering the modbus comms? Have you got multiple modbus nodes?

Hello @TotallyInformation and thank you for replying.

Thanks for the hints. It could be a good starting point for my problem.
Unfortunately, I don't have access to the Node-RED logs. I've already asked the OEM manufacturer to give me access to the Node-RED logs, as this makes it difficult to detect the issue.
