[mythtv-users] Fixes 30 Comms lost between front and back ends

[John]

Have been using fixes 30 since release on Ubuntu 18.10 then 19.04 
without any reliability issues.

However since updating from

18/03/19 MythTV Version : v30.0-28-g60cfb7c05aa

to

14/05/19 MythTV Version : v30.0-51-ga32ec4bdea

I have had two occurrences of the backend dropping the self hosted 
frontend and refusing to reconnect to any other.

Recordings continue.

Looking at the change history there are no obvious  candidates and a 
bisect will probably take a month as the fault rate is low.

Anybody else seeing similar issues?
