Messages in log while closing app

Hi, using Wfview on Bookworm Pi, client 2.11, server 2.3, radio 7300.
When closing the client, I get lots of these lines in the log:
2025-05-12 16:55:48.648 WRN rig: Rig (FA) error, last command sent: “S Meter” (min: 0 max: 255 bytes: 0 ) data: “15 02”
After this cluster of error messages, the client closes as usual.

Should I worry about this?

I assume you switch off the radio before closing wfview? This is just the response from the radio that it can’t handle commands while switched-off.

You can safely ignore these.

Yes, doing it in that order.
Thanks
