For the sake of completeness: The BlueOnyx was created from the vz
template sometime in Q3/2009 and then I imported all sites that are
currently on it from a strongbolt installation running on a RaQ4. Since
then nothing probably has changed, so I assume it messed up during the
imports of the existing sites. Unfortunately this is pretty long ago and
I have no backup showing the exact messages when it messed up. Should it
happen again, I'll happily supply you with all information needed.
So far I haven't seen this problem on any of the other BlueOnyx servers
we run (quite a few).

Cheers,
Christoph
