Aerotriangulation endless processing loop

Dear Bentley Community,

Usually everything is working fine until the last aerotriangulation... the engine is stuck with one process.

The percentage progression starts an endless loop from 66% to 74% and again 66% to 74% and again and again...

The problem is that I don't have error message or "real" fail because of the endless loop

Do you have any ideas or solution ? 

Best regards
