Calling boost::asio::io_service run function from multiple threads

In my server application there is a pool of threads calling the io_service run() function. When a handler throws an exception the run function throws that exception too. Multiple threads call the run function in a try catch block. To restart the event handler I need to call run again but the documentation stated that restart() has to be called first. Restarting the io_service must assure that all run calls has been finished. How can I do that when other threads are still calling the run function?

No the documentation does not say that. You need to reset once the service had run out of work/been stopped. You did neither, so you do not need reset there.

Simply do as explained in this post Should the exception thrown by boost::asio::io_service::run() be caught? (which links to the docs)
