Hi,

doesn't know your app, but it seems to me that there is a pending timer that 
returns a little to late. If a timer is canceled it "returns" with error 
code boost::asio::error::operation_aborted error code even if the scheduler 
is already stopped. Cancel all your timers first and then stop the 
scheduler.

Pirx!
