It seems that you call io_serivce::run() before any async operation
was issued. In such a case, run() just exits immediately, as I
explained in one of my previous comments. In order to avoid such a
behavior,
associate io_service::work object with this io_service:
http://www.boost.org/doc/libs/1_55_0/doc/html/boost_asio/reference/io_service.html
(scroll down)

In general, it's highly recommended to read the Asio documentation -
all these issues are described there.
