Hi,
Thank you very much! This was indeed the problem. There was copy of the
object handed over too an other object with a "this" pointer so i didnt see
it and was than initializing a shared_ptr. Now it is handeld correctly a my
program is shutting down in the right way. 
Again thank everyone for your helping hand!
