<div>Any thoughts on what might be causing them?</div>

</div>
<div>I can trace the errors back to Oct 16 last year (could be
sooner, but that's where my archived logs end) - meaning I was
experiencing the errors on both fixes/31 before my upgrade to
master (which occured March 6 2021).</div>

<p>I would guess that you have a hacker or some rogue process that
is sending messages to your mythtv box. Is your port open to the
internet? Port 6543 is normally the MythTV port. You can see these
errors if you run telnet localhost 6534 and then type random junk
into telnet. Each line of stuff you type will be reported as a
protocol error in mythbackend (unless you by chance type a valid
MythTV command :).</p>
