Nodes become unresponsive after a while

[vie5i]

After a few hours of normal operation I've noticed since v4.08 the nodes become unresponsive.
They do not send messages through.
I don't see anything wrong.
I can modify and deploy the software but when I send a command it does not go through which means commands don't get sent through.
Restarting it does make it responsive again but then after a few hours same issue occurs.
Please see the screenshot attached.
I have injected a boolean true but it does not go through to debug.

Welcome to the forum @vie5i

Are you using charts in your dashboard? If so then work out the total number of points stored in your charts when a few hours has elapsed. If you find that is many thousands then that is probably the problem. For example, a chart with four lines with data every second, would be 14000 points per hour, so if you have specified a time span of 4 hours that would be approaching 60,000 data points which have to shuffled down in the browser every second.

If it is not that then run a system monitor on the machine and see if something is hogging up the processor.

Thank you for the reply.
I am using charts.
Points update every 15minutes.
Node-red was hogging up the CPU.
I disabled all charts the CPU eased off.
Hopefully that was causing it.
Will monitor over the next few days and see the results.

Hello,

I found I had created a loop which went unnoticed, this was causing node-red to use high CPU upwards of 90%.
This would also make the client machine browser to use high CPU.
It has now stabilized and node-red is using round 5% CPU.
I hope somebody else finds this useful.
