I'm seeing something similar to this (messages more like those in underlying debian bug report) - in this case triggered by a script which sshs in (invoking unison) twice in quick succession. Underlying hardware is an ARM board which may a little slow, don't know if that helps to trigger race?
I'm also a little confused as to whether socket activation is the default under Ubuntu or not. My etckeeper history suggests it's been enabled here since 2014, when records began .. so no idea if it was something I enabled or not!
