I've had a look at /var/log/messages but nothing seems wrong except
messages like this one:

--8<---------------cut here---------------start------------->8---

Aug 21 14:48:42 localhost shepherd[1]: 6 connections still in use after sshd-13752 termination. 
Aug 21 14:48:42 localhost shepherd[1]: Service sshd-13752 (PID 29977) exited with 255. 
Aug 21 14:48:42 localhost shepherd[1]: Service sshd-13752 has been disabled. 
Aug 21 14:48:42 localhost shepherd[1]: Transient service sshd-13752 terminated, now unregistered. 

--8<---------------cut here---------------end--------------->8---

Is it useful configuring the monitoring service [1] on milano-guix-1 to
have useful data in the logs in case we get a similar issue?

Thanks, Gio'
