[mythtv-users] frontends starved to death

Wed Aug 31 01:54:17 UTC 2011

Hello All,

I am not sure what is going on with my setup, but I am having problems where
my frontends get starved for frames.  This almost always happens when
watching live TV, but I do see small recoverable starvations when watching
recorded content.  My setup is a fresh install on Mythbuntu 11.04 with Ron
Fraziers Ceton patch.  I have a gigabit network with a modern triple core
AMD backend and five Atom/ION frontends.  Below is an example output of my
logs.  For the record, I have no idea what my kids were watching, "My Wife
and Kids "Of Breasts and Basketball"", but channel 2033 is Nickelodeon so
keep it clean guys!  ;)
