Concurrent login / daemon-reload produces abandoned sessions

[nicolasbock]

Using systemd-248.3-1ubuntu1 on Ubuntu Impish the following script produces multiple abandoned sessions:

$ for i in {1..100}; do sleep 0.2; ssh localhost sudo systemctl daemon-reload & ssh localhost sleep 1 & done
$ sleep 2
$ jobs -p | xargs --verbose --no-run-if-empty kill -KILL
$ systemctl | grep abandoned
  session-174.scope                    loaded active     abandoned Session 174 of user ubuntu
  session-175.scope                    loaded active     abandoned Session 175 of user ubuntu
  session-176.scope                    loaded active     abandoned Session 176 of user ubuntu
  session-25.scope                     loaded active     abandoned Session 25 of user ubuntu

I would like to debug this behavior further and understand why this is happening but don't know where to look next. Is there any information in particular I should look at?
