cannot shutdown my computer: Stopped LSB: Started kernel based NFS daemon

OpenSUSE 12.3 X86_64

I cannot shutdown my computer anymore.
I have a NFS server running on the same computer but that was never a problem until now.

When I shutdown the computer as user I get this message:
Stopped LSB: Started kernel based NFS daemon

Thought it could be a rights issue but I also cannot shutdown as root.
