Description (partial)

When a module is the only one with PIM6 enabled on it interfaces and it connects to a large number of PIM6 neighbors with a large number of groups per neighbor, then reloading the module can cause subsequent PIM6 interactions with M6RIB to fail permanently, causing traffic loss.

The problem was only seen with 200 PIM6 neighbors on the module and 40 groups per neighbor. It was not seen with 30 groups per neighbor.
