You're killing mythfrontend in the middle of the MythMusic database schema
upgrade (specifically--at least in the logs provided--during the backup it's
making before the upgrade).  If you let it run farther in any previous runs,
it may have gotten into the middle of the upgrade, at which killing
mythfrontend may have done bad things.  Remember that the
backend/mythtv-setup upgrades the TV schema.  All plugin schemas are
upgraded by the plugins themselves, which run inside the frontend.

In other words, you need to look at more than the last line in the
log--2 lines before it said what was happening.

Nov 10 08:48:46 Master-Backend mythfrontend.real: mythfrontend[6935]: E
CoreContext dbutil.cpp:604 (DoBackup) Backing up database with script: 
'/usr/share/mythtv/mythconverg_backup.pl'

So, you just need a bit more patience when upgrading versions, because
backing up the database takes quite a bit of time, even if the upgrades go
quickly (and they don't always).  (And, yes, ideally mythfrontend would tell
you what's happening, but until someone completely
redesigns/refactors/rewrites our database upgrade code, we don't have access
to the (new) UI at the time when we're doing the upgrade, so we can't put up
any messages.)

Sorry for top posting earlier


Mike,


I restored the original database again. From version 0.27 Schema was 1317 I
think.

I then let mythSetup run for about an hour then mythbackend also for a
while.


I then reran the frontend and it did the same as before. Only this time I
did not stop it. But when I returned to the box it was no longer running ,
determined this by checking TOP.

The last log is that the backup was completed.

Logs below
