I actually figured it out. I rand mythtvbackend in foreground mode and
waited for it to die. It gave me file limit exceeded. Which has to do
with the ulimit. Apprently it got reset to a number insted of
unlimited.

Once i changed ulimit -f unlimited  it has fixed it.

After looking through source i determined that the funky usleep error
has to do with no disk space, but if the file size limit is reached
then it will hit that "limit"

Thanks.
