I think i found the solution, I had to allow multithreading on the Model

[Thomas]

I think you've found the right solution. Whenever a context (or its managed objects) is accessed concurrently by different threads, the multi-threaded access needs to be enabled for the model. Otherwise there is no synchronization, potentially resulting in symptoms as described by you.
