Tracking down a WARN message in log

I keep getting this WARN message in my log.

2021-05-10 12:14:48.383 [WARN ] [o.internal.handler.SysteminfoHandler] - No information for channel process#load with device index 764 :

How can I track down what this is?
It looks a bit like an error with the System Info binding which has a channel for process load??
I only have one System Info device, my Raspberry Pi. And I don’t use/haven’t set up the channel for this.
