I'm guessing you use KDE and this may be a problem in the default way KDE
treats the output of the "wall" program. I don't have a KDE setup to test
with, but try looking at KDE's System settings -> Common appearance and
Behaviour -> Applications and System notifications -> Manage notifications
to find out what is happening.
It may also be something in your mesg y/n setting. What does "mesg"

Its systemd trying to "help" you. OpenSUSE 13.2 includes a delayed UPS
shutdown script in /usr/lib/systemd/system-shutdown/nutshutdown . I
suggest you comment out the command in that script.

Endless repetitions of (Communication lost - Communication
re-established): its been reported before in this mailing list for various

issue in this mailing list with a specific technical description.
