I have a package called 'check_ds.pl" or something like that, it can 
monitor multiple daemons, and restart them if needed. I find my 
mythbackend needs to be restarted at least once a day, if not twice. 
This seems to do the trick, I run it from cron once a minute. I can post 
the script (it's just a perl script) if anyone wants it.
