If multipathd doesn't become a real time process, it was scheduled as a normal process, without any priority increase. Bump up the CPUWeight so that even as a normal process, it will still run with increased priority. If multipathd did become a real time process, it set itself to the highest priority, which is excessive. A priority of 10 is plenty.
