[mythtv] Commercial flagging, shutdowns & lost recordings

[Matthew Carle]

I posted this in the mythtv-users list but didn't get a reply. This is in
0.18.1

This is a problem I noticed a while ago but it has happened to me twice in
the last couple of weeks. It seems like it would affect most people who use
commercial flagging and have their backend set to shutdown when inactive.

At the end of a recording, the system prepares to shutdown. Commercial
flagging starts but doesn't interrupt the shutdown process. I see this sort
of thing in the log:

2006-01-22 23:20:03.151 I'm idle now... shutdown will occur in 240 seconds.
2006-01-22 23:20:12.170 230 secs left to system shutdown!
2006-01-22 23:20:22.192 220 secs left to system shutdown!
2006-01-22 23:20:32.213 210 secs left to system shutdown!
2006-01-22 23:20:40.120 Starting Commercial Flagging for "Out of Sight"
recorded from channel 1015 at Sun Jan 22 20:24:00 2006.
2006-01-22 23:20:41.118 New DB connection, total: 1
2006-01-22 23:20:41.166 New DB connection, total: 2
2006-01-22 23:20:42.233 200 secs left to system shutdown!
2006-01-22 23:20:52.256 190 secs left to system shutdown!


When the countdown has finished, it appears to decide to wait for the
commercial flagging to finish. So more than an hour later, we get this:

2006-01-23 00:33:55.566 Finished, 5 break(s) found.
nvram-wakeup: Do NOT write into nvram. Wake Up time must be
nvram-wakeup: at least 10 minutes in the future.


There was actually a recording scheduled to start at about this time, but it
shut down anyway. Additionally, because nvram-wakeup didn't write to the
bios (the next wakeup must be at least 10 minutes in the future), it won't
wake up for any future recordings - you have to manually power it up after
one of these occurrences. This could cause the loss of many recordings if
the mythtv box isn't used for a longer period. I have also had it do what
seems like a similar thing while I was watching a recorded show. Does this
happen to anyone else? Has it been fixed in 0.19?

Thanks,
Matthew.
