Comment:

 The descriptor_data variable is only set to NULL when the corresponding
 socket is deregistered (see epoll_reactor::deregister_descriptor, which is
 in turn called from reactive_socket_service_base::destroy/close). This
 means that your program has closed the socket or destroyed the socket
 object.

 Most likely you have a threading issue in your program where you close a
 socket from one thread while simultaneously starting another async
 operation on the same socket from another thread. If you are sure this is
 not the case, please attach a small, complete program that exhibits the
 problem. Thanks.
