After another reboot, the system came up now.

And what I see is that nodes occasionaly loose their users. I haven't
seen that the two month while testing (of course there were no real
users during that time, so I'm not 100% sure that it did not happen).

Could that be the cause of the trouble??

Kind regards,

  Torsten
