Stephane, did Nadia's post help you with things, or are you still trying to figure things out? Likely going to need a larger set of the log entries in order to try to provide further information, as the errors by themselves are often not enough to really tell what is going on, we also need the Information messages to put things into context, but that would require you run the QVS logging at the High level to get those, so if you are not, that would be the first additional thing I would recommend doing, increase the log verbosity. Sorry I do not have anything better at the moment.
