Comment # 3 on bug 958346 from Robin Roth

Thanks for the hints. Since looking into the issue we have log-level=debug as
well as some custom monitoring on all machines and try to catch one that fails
"in-the-act".

There is no pattern to the machines failing, desktops of different hardware, a
server. We now have a machine on 13.2 with the same symptoms.

One thing that is common to all machines is a custom service running that has
an underscore in it's name. CoreOS had a bug, but that's code that is as far as
I understand is not present in openSuSE
