I'm running JD as well (w/ultimate paid add-on), and have seen this issue infrequently/intermittently, but not at all consistently. It may well be an issue of JD not consistently waking up services it has put to sleep to save battery life.
Maybe that's my issue too thou I would swear it didn't show up until I enabled supercharger....
It happens when waking the p phone out of sleep.
