I am not sure if I understand your question, but sheep_get_fd() will NOT call connect_to() for free cached FDs. Only if all the cached FDs of one node are all used by other threads, it temporarily create a new connection that will be closed by subsequent sheep_put_fd(). This design prevent FD from being concurrent accessed by more than one threads at a time. Thanks, Yuan -- sheepdog mailing list [email protected] http://lists.wpkg.org/mailman/listinfo/sheepdog
