Hello list,<br><br>Right now i am having some problems  with a TCP socket waiting for a pending async read operation. When the remote endpoint closes the connection due to some crash or other unexpected situation(i.e, without proper closing of the socket) my application is terminated with this message: &quot;Terminate called after throwing an instance of &#39;boost::exception_detail::clone_impl&lt;boost::exception_detail::error_info_injector&lt;boost::system::system_error&gt; &gt;&#39;<br>
  what():  Transport endpoint is not connected<br>Aborted&quot;<br><br>Maybe i am missing something here, because i expected any boost::system exceptions to be passed to the callback associated with the async read operation. I am assuming that this exception is thrown in the io_service::run method, is that right? If so, why it is not passed to the callback? and what can i do to catch it, having the io_service::run running on a separeted thread?<br>
<br>Thanx in advance and best regards,<br>-- <br>Matheus Araújo Aguiar<br>Computer Scientist<br><a href="mailto:matheus.pit@gmail.com">matheus.pit@gmail.com</a><br>
