Hi Dmitry
thanks.
I guess like anyone else, I have issues with Maya once in a while. 
But with a few exceptions, nothing extraordinary.
The one big exception is that I cant get RT GPU to work, but I think that is unrelated to this (?)
Maya Autosave? where is that?
I need more testing to check if the crashes are related to maybe distributed rendering or renderlayers.
Is there a more recent Vray Built I coud try?
