Well....some kind of heartbeat running in cron on the slaves that
tries to ping the master server, and if it fails, recycle the
mythbackend process. Now you are at the mercy of the network though.
You could also try to do some kind of TCP connection from the slave as
a test of the backend. Or if you want to get even more fancy, have a
cron on the slaves that gets the uptime from the master and if it is
less than the previous value, recycle the mythbackend process. As they
say in perl, there is more than one way to do it.
