Of course this makes any TV watching on the frontend very painful, usually the frontend starts complaining that its lost connection to the backend. Which is actually still running but dog slow. This has happened twice today and both times restarting the backend fixes it for an hour or so.

Bump, still seeing this problem. Seems to be only when watching Live TV,
but the problem is intermittent so its hard to be sure.
