Debug sidebar messages disappear automatically

I user node-RED v3.0.2. Since some time I have problems with disappearing messages in the debug sidebar. Maybe I have configured this somewhen, but I can’t remember where and how to turn it back. Does anybody know how I can change this timeslot to keep messages without disappearing?

Thanks alot

Hi and welcome to the forum.
(Just to mention: You will be limited to how many posts you can make at the start)

Good news / bad news.

Alas they are supposed to do that, but the supposed to part is annoying.

If you have a lot of them in/on your flows there is only a certain/fixed amount of buffering allocated to them.

So once that memory is full, they just wipe.

I'm guessing you have it set to only display current flow and not all?
(Well, that's what I have and that's what happens for me and why.)

Alas it has not been addressed and still happens with newer versions.

The best/only way to stop this happening - I believe - is to turn off all the other debug nodes on other flows.

Sorry, but that's the best I can offer.

Select All at the top of the debug pane to see what is spamming the browser with loads of messages.
