Hi,<br><br>yu have to start the io_service only once. But make sure your io_service stays running. The event loop stops running when there are no more items in its queue. <br><br>That means if you return from your timer without starting a new timer it will return immediately.<br>

<p class="MsoNormal">I
have a question regarding the asio::deadline_timer  , it seems I need to
run the  ioservice.run() all the time in order to update the timer, which
is seems undesirable. Any idea how I can just start the timer and  wait
for the callback instead?</p>

<p class="MsoNormal">I was playing around with this today too. It seems that you
only need to call io_service::run() once (that will start the timer).<br>
