I was suprised to find the following messages: "29/12/2010 10:45:20";"Change to operating mode 'online'."; and "29/12/2010 10:45:24";"Connection established: Connection_1, Station 10.10.212.10, Rack 0, Slot 2." WITHOUT the presence of the opposite messages ('Offline'; 'Connection lost (or something)) preceding them. Is this possible and how? What could have happened? A power loss of the PC could explain, because there also is a "Log initialization ended" (but not the "Log initialization started") message. Are there also other scenarios that could cause these messages to appear? Thanks in advance, Willem
