kernel messages on UI during run - runs seem unaffected

Project help Fold for Covid

Hi,

I’m periodically (10-20mins) seeing kernel messages in the console UI regarding networking, I think it’s possibly related to docker, but don’t know enough about it yet to troubleshoot.

I’d be interested if this is normal, or if anyone else is seeing it:

For information should anyone else be experiencing this:

The messages relate to networking which is unfortunately via wifi.

I’ve played around with channels as per the FAQ and changed between 5 and 2.4Ghz bands, no change.

Interestingly I can now recreate this by plugging in a monitor to the mini HDMI port OR logging in via the local web interface. Given both of those are somewhat unrelated I’m starting to suspect its load/heat related.

A constant ping to the pi is fine until I do either of the above. Accessing the web UI usually results in the pi eventually becoming disconnected from the network and flashing the green LED 4 times.

This Pi is in one of these heatsink cases, but no active cooling: https://shop.pimoroni.com/products/aluminium-heatsink-case-for-raspberry-pi-4?variant=29430673178707
