Hmm, I still have the problem.
/var/log/open-xchange/open-xchange-admin.log.0 tells me:
This error shows up many times. But another error shows up as well, just seconds before.

Does this have anything to do with Debian/Ubuntu on one side and OpenSUSE on the other? Why does the admin daemon needs apt-get?
SEVERE: java.io.IOException: Cannot run program "apt-get": java.io.IOException: error=2, No such file or directory
