Hi,

Im sorry, I didnt had time yet to regard what is happening in detail
with my simulations and give you a more elaborated answer. Im terribly
busy these times. Anyway, from past simulations for which I encountered
the same error messages, I think Im having some particles escaping to very
large distances, as suggested by Ives, and that is the cause of my troubles.

To fix this, I think you must remove these particles by hand and then reestart
the simulation ...

Cheers, H.
