Multiple instances of mythbackend seem an independent problem for me.

Immediately after a reboot I have

--8<---------------cut here---------------start------------->8---
ps ax | grep mythbackend
 1675 ?        Ssl    0:00 /usr/bin/mythbackend --daemon --pidfile /var/run/mythtv/mythbackend.pid --syslog local6 --verbose http:debug,up
 2648 pts/0    S+     0:00 grep mythbackend
--8<---------------cut here---------------end--------------->8---

The mythbackend process uses the arguments specified in /etc/default/mythtv-backend.

I also noticed it and I have no idea when and how the process with the
loglevel of crit was started.

Done, as you can see above.

I skipped this step because after the reboot the backend is definitely
running (confirmed by systemctl status mythtv-backend)

An attempt to connect to http://localhost:6544/ was done at 17-13-53 but
left no trace in the log. Actually I expected this: the problem is that
the port 6544 for some reasons is not opened by the backend.

I'm looking forward to your comments.
