The session processing messages are not bugs.
This is inline with the behaviour of sytemd-210.
For an explanation see comment #50.

The logs in this report show that there is a very frequent session creation
(multiple new sessions per minute).
In this case, I would recommend to activate session lingering as described in
comment #56.

The message:

systemd[26233]: Failed to open private bus connection: Failed to connect
to socket /run/user/0/dbus/user_bus_socket: No such file or directory

might point to a dead user session.
For further investigation, I would need a new bug report with verbose systemd
logs when the problem appears.
