There are at least QP/C++ [2] and SObjectizer [3].
All three frameworks are used in production, especially QP/C++.
Error handling in C++ actor frameworks is a different topic than such handling in Erlang or other safe language. Because if you do something like division by 0 or deference of null pointer in your C++ actor you will have a different result: in the best case the whole your application will crush, not just one actor.
