yes I too feel that you are right, and I think that the problem is with the shared_ptr (shared_from_this()) . Can anyone suggest a way to reduce the shared_ptr reference count at the end of the thread execution, so that all referece will be reduced and the respective destructor will be called.

But it never gets called! But if call a join from someware else (th->join()) the destructor of the TCPConnection class gets called and the connection is terminated, otherwise the it continues in the connected state!! What could be the mistake I am doing? If not mistaken that's the normal behavior which requires parent thread to join() its child threads, for proper release of thread resources, and I don't think it is specific to Boost.Thread. I might be wrong though. Thanks, Lloyd What kind of waist? I guess the name of the function mislead you. join() in this context means "wait" - nothing more. _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users ___________________ Happy New Year 2010 _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users ------------------------------------------------------------------------------ _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users ___________________ Happy New Year 2010
