I'll agree with that. I created /etc/dbus-1/system.d/my_system.conf containing

<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-Bus Bus Configuration 1.0//EN"
 "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd">
<busconfig>

  <limit name="max_connections_per_user">100000</limit>
  <limit name="max_pending_service_starts">10000</limit>
  <limit name="max_names_per_connection">50000</limit>
  <limit name="max_match_rules_per_connection">50000</limit>
  <limit name="max_replies_per_connection">50000</limit>
</busconfig>

I then logged out, rebooted system, and systemctl status sshd.service works.

The above workaround also fixes my problem with auto mounting any USB devices/memory sticks...

you could post that to the other bug, will remember for mount issue, maybe we have already some bugs too
