The first LOR after reboot seems to be gone. All the actions I performed to create the first LOR do not throw one anymore. So this one seems to be ok. Thanks for that! The second LOR when rebooting/shutting down is still there in a slightly altered form. Seems to be the same type of problem as the first LOR. See excerpt from logs below.
