I'm not sure what the image is showing me, but unless the impellor tip speed is around 7m/s you have a problem. 

Are you adding particles constantly, or only for a short period? How does the flow field look prior to it failing? Is the failure repeatable, or can you restart from a saved case & data and run beyond the initial failure time?
