----------------------------------------+-------------------------
 On my system (fresh installed Ubuntu 13.04), since the introduction of
 MythLogServer, there are always multiple instances of MythLogServer coming
 up in a very short time. Each of them eats up as much CPU as it can get. I
 had to add a cron job that kills all instances of MythLogServer each
 minute, so there are only 1-3 running at a time, nevertheless, the CPU
 load is always at 100% and my living room is always pretty warm.

 If you google for it, you see that there are/were other people who seem to
 have the same issue. One of them was talking about NVIDIA driver
 version... I did not try changing the native NVIDIA drivers yet, because I
 don´t have any other issues with it, and I can´t really believe the
 graphics driver is related to logging.

 This is my process list, filtered, about 8 minutes after the last kill (I
 changed the upstart script parameter of MythBackend to --nodblog, because
 I thought that would perhaps help, but it didn´t)
