OF16ext GGI - divergence after a rotation of ~ 180 degree

I am trying to run some simulations with the OF16ext and ggi.
I have an outer field where all boundaries set to zeroGradient. (Velocity and pressure)
I have an internal rotating mesh with a fixed rotational speed of 300 rounds per minute.
At the beginning of the calculation everything goes fine. But at an angle around 180° my simulations just gets totally wrong.
see this gif animation:
My thought is the problem lies within the ggi pair which gets posted in the log file. The values are growing by the time steps. Does anyone know what exactly this ggi pair logging says?

I would suggest first of all to check how the mesh looks like at the end of your simulation. From what you say, I think your mesh did not slide properly.
