[one-users] oned keeps dying without a trace (2.0.1)

[florian.feldhaus at tu-dortmund.de]

Hm. That gives us more hints, but unfortunately I don't understand
OpenNebula deep enough to be able to debug the problem from the segfault.
Best idea would be to try out the newer version of OpenNebula (e.g. 2.2)
and see if the problem has been fixed there... Otherwise, you need to wait
for feedback from the OpenNebula team.

Cheers,
Florian
