Pair of runaway recordings.

TVService had crashed, starting the frontend showed garbage and no way to kill the recordings. Tried stopping the service directly from XP services control and it wouldn't, only restarting the PC at around 23:25 shut it down.

I was playing QuakeLive on the server PC when it failed and that's probably what triggered MySql to fall over. Would be nice is if losing the db didn't lock the tvservice like this.

Hi Paul Shirley

There is nothing we can do about such a report as you have not provided the logs. Please post logs as per our support thread rules.

My mistake, attached as a 7z the 1st time.

Hi again Paul

If MySQL did indeed fall over (I can't tell this without the system event log) then TV Server certainly followed it down:

TV Server is always going to struggle if the DB goes down. After all, all the scheduling information, all the program information, all the channel information... its all stored in the database. If TV Server doesn't know when a schedule is meant to stop then isn't it better that it keeps recording? That way at least you don't miss the recording.

I'm not complaining (much) that TVservice fails if the db goes down, the problem is how badly it goes down. Continuing to record is a reasonable option, though one I'd prefer is stopping at the last stop time it grabbed from the db because a full drive is never good.

It's needing to reboot the entire PC to clear the error.

I needed to restart in a hurry or I'd have tried restarting the MySQL service to see if that unlocked TVService. There's a problem though, XP will try to stop dependent services 1st and I don't know if that can complete if TVService refuses to shutdown. Really need TVService to always be stoppable, whatever happens.
